The ships were originally known as "stealth frigates" due to their unique stealth design at the time. Their reduced radar cross section is achieved by a clean superstructure compared to conventional designs, angled sides and radar absorbent materiala composite material of wood and glass fibre as hard as steel, light, and resistant to fire. Most modern combat ships built since the introduction of the La Fayette class have followed the same principles of stealth.

All information gathered by the onboard sensors is managed by the Information Processing System, the electronic brain of the operation centre of the ship. It is completed by an electronic command aid system. The La Fayette class has space available for the future installation of the Aster 15 air-defence missile, however they will not be installed due to recent cost issues.

France ordered five ships of the La Fayette class inthe last of which entered service in In the late s, the Marine Nationale started the studies for frigates adapted to low-intensity conflicts in the post—Cold War era.

The ships were to serve in the large French exclusive economic zone EEZbe adapted to humanitarian operations or low-intensity operations in support of land troops, and replace the aging D'Estienne d'Orves -class avisoswhich tended to prove too focused on naval operations and were ill-suited for joint operations.

Conventional warships used in low-intensity or humanitarian relief operations proved costly, with their heavy equipment and large crew. Hence came the requirement for lightly armed frigates with economical engines and small crew.

In Italy, the same requirements led to the development of the Cassiopea and Minerva type corvettesbuilt according to both civilian and military standards. These ships were limited to 1, tonnes because the limited size and depth of the Mediterranean and the proximity of the homeland.

To be enduring enough, the ships had to reach 3, tonnes, the size of a frigate. The larger displacement allows combining strong firepower like the Minerva class and a capacity for a medium helicopter like the Cassiopea classalong with a good autonomy and seaworthiness.

These ships are high endurance units designed to be operated in overseas possessions the Caribbean, Polynesia, and New Caledonia and the EEZ, where the likelihood of a naval threat is low. The speed is limited to 20 knots because of the low-power engines which emphasises autonomy and reliability. The niche for more hostile environments is covered by the La Fayette type, designed to operate in complex zones like the Indian Ocean or Djibouti.

These ships were to be able to secure the EEZ, but also to operate in naval groups or intelligence gathering missions.

The intended role for the ships was in fact very varied, because the experience of the C. It took several years to refine the concept, and the first ship was eventually launched intwo years after the final design was completed. Weapon system testing took place inand particularly extensive trials were undertaken to prove the structure of the ship under a wide range of conditions. La Fayette was eventually commissioned in March At the time of their commissioning, the units of the La Fayette class were the state of the art in stealth for warships.

The shape of the hull and the superstructures is devised for the optimal reduction of the radar signaturewhich has been reduced by 60 percent: a tonne La Fayette unit has the typical radar signature of a tonne ship. The superstructures are built using radar-absorbent synthetic materials.

Their radar cross-section is equivalent to that of a large fishing boat, which can make camouflage among civilian ships possible; or that of a much less capable corvette, which could lead an enemy to underestimate the capabilities of the ship.How does Ramit Sethi, author of the New York Times bestselling book I Will Teach You To Be Rich, achieve conversion rates as high as 68. Contrary to most marketers, he will actually ask subscribers to unsubscribe from his email list. As someone who charges a premium for his course material, he wants to weed out those who treat his content as a commodity.

For example, as your customers are using your product, send a simple email asking if they were at first pessimistic of the product. If they were, then you can ask for the actual results that they were able to achieve along with detailed objections that your customers had before choosing your product or service.

Gary Vaynerchuk has a great talk about the ROI of Social Media and he compares to the ROI of your mother. She knew what you liked, what you hated, and when to give you some time. She never asked for anything back. She only loved you like any good mother does without ever needing or wanting anything from you only for you to be your best.

Tony Hseih, CEO of Zappos, built a billion dollar company based on this theory. Early on, Zappos understood the power of word-of-mouth marketing and made it a company focus to provide excellent customer service no matter the costs. In the end, we need to stop treating customers like metrics and more like people. Treat them right and never ask for anything in return and then reap the benefits. When Neil Patel started his SEO agency, he targeted major publications such as Techcrunch and Gawker and offered his services for free.

In exchange, he asked for a badge on their websites that linked back to his website. He also used these clients as case studies which allowed him to have the social proof he needed to land even more clients. Take a tip from Neil and be willing to exchange your services for a raving review.

Then leverage that review for more, higher-paying gigs down the road. Sometimes the easiest way to get a testimonial is to simply ask for it.

Iterative grading was helpful. Thank you so much Professors for this useful course. I very much liked XLMiner, it is indeed a very simple yet powerful toolI was really impressed with the clarity, knowledge, engagement level, and patience of the instructor.

His contribution in the forums made this the most useful online learning experience I've had (and I've tried a few different venues)I like the course very much and the material given to us was excellent. I enjoy very much learning about simulations and using Cristal ball software. Also this course has given me valuable information about how to approach a risk analysis, and the software model assistant is very interestingI found it challenging but also a rewarding experience.

After completing this course I am now more confident about undertaking statistical analysis. Since I started the Epidemiology Statistics class, I've had a much better understanding of the other staffs' concerns. A very nice introduction to the subject. As someone without any real background in epidemiology, now moving into an area where I need it, this course was very helpful indeed. This course is a great review of some popular probability distributions and how to test their assumptions.

Reviewing the sampling techniques and testing the assumed distributions will help me when I check data and perform regression models. I appreciated the discussion board feedback as well as comments back on the homework assignments. Both of those things have helped me become a more efficient programmerDr. Pruim was an outstanding instructor, extremely knowledgeable, respectful and prompt. This course has given me a strong foundation for continued learningThis is really a fantastic course.

The materials were well done and the exercises really helped me develop and apply the concepts. Very, very well done. I will recommend it to my colleaguesI was very impressed with how well Randall Pruim interacted with the class through the discussion forum. I also was pleasantly surprised at how smoothly all the logistical "on-line" issues went.

I have already signed up for another courseI like the format of those courses. There is a lot to learn, but it's concentrated on the key points. For somebody working full time it beats a semester-long course. Great pace to the course, nice and concise within 3 weeks, enjoyed the discussions, HW was not too intense and time consumingIt will help me to better understand the methods behind statistical analysis used for conducting research and publishing data.

I enjoyed the course. It's really convenient to do assignments on my own time. As always, professor Everson always provides nice feedback and suggestions to help understand the concepts very well. I hope to take up lot of other courses which she teaches.

I am looking forward to many other courses along the way. All of the courses I have taken through Statistics.

I learned more in the past 6 weeks than I did taking a full semester of statistics in college, and 10 weeks of statistics in graduate schoolI really like the Statistics. Just before I signed up for the first course, I had tried to work my way through a couple of different textbooks, and just could not get anything out of them. With this class the clear discussion text, relevant assignment problems, and instructor feedback made it easy to learn.

Meena Badade is great at answering student questions with very clear explanations, and Poonam provides excellent feedback on the homework assignments. Thank you both for a great course.Someone who is courteous, kind and respectful. When apologizing for an issue, a gracious tone is everything. In short, being gracious disarms people even irate complainers.

Yes, this example would have been more impactful if Madison shared immediately rather than nine months later. Signing responses to reviews with your name establishes a personal connection and shows that a real person is taking accountability for any issues.

For example, a customer is unhappy with the price of your product or misunderstood what you do. In these cases, politely bring clarity to the situation. Now, readers who skim through these reviews know that the coffee and bike shop prides itself on having single-origin roasts.

And they could very well attract people who want to pay more for the best espresso in Seattle. Knowing how to apologize is a must-have skill when responding to reviews.

To inspire people to change their minds, you need to act, too. Specifically, you need to go above and beyond what people expect from good service. For example, if a couple complains about a hair in their food online, they expect the restaurant to apologize profusely.

To really impress people, the restaurant needs to exceed expectations by offering free entrees next time they visit the restaurant. In the case of the Regatta Inn, a small bed and breakfast on Nantucket, the manager offered a free off-season night to a couple on TripAdvisor who had issues with the heat in their room during a short stay.

The manager, Linda, offered a free night in person, but she reiterated it over TripAdvisor and even thanked the reviewer for the reminder to fix the issue all with a sense of humor to boot. You get to decide whether they make or break your business. By taking the time to resolve issues online, you show your community just how much you value every customer.

A statistic (singular) or sample statistic is a single measure of some attribute of a sample (e. A statistic is distinct from a statistical parameter, which is not computable, because often the population is too large to examine and measure all its items.

However, a statistic, when used to estimate a population parameter, is called an estimator. For instance, the sample mean is a statistic that estimates the population mean, which is a parameter. In calculating the arithmetic mean of a sample, for example, the algorithm works by summing all the data values observed in the sample and then dividing this sum by the number of data items. A statistic is an observable random variable, which differentiates it both from a parameter that is a generally unobservable quantity describing a property of a statistical population, and from an unobservable random variable, such as the difference between an observed measurement and a population average.

Statisticians often contemplate a parameterized family of probability distributions, any member of which could be the distribution of some measurable aspect of each member of a population, from which a sample is drawn randomly.

\

For example, the parameter may be the average height of 25-year-old men in North America. The average of the heights of all members of the population is not a statistic unless that has somehow also been ascertained (such as by measuring every member of the population).

The average height that would be calculated using all of the individual heights of all 25-year-old North American men is a parameter, and not a statistic.

Important potential properties of statistics include completeness, consistency, sufficiency, unbiasedness, minimum mean square error, low variance, robustness, and computational convenience. Information of a statistic on model parameters can be defined in several ways. The most common is the Fisher information, which is defined on the statistic model induced by the statistic.

Kullback information measure can also be used. From Wikipedia, the free encyclopedia Jump to: navigation, searchFor other uses, see Statistics (disambiguation). This article needs additional citations for verification.

Mathematical statistics is the application of mathematics to statistics, which was originally conceived as the science of the state the collection and analysis of facts about a country: its economy, land, military, population, and so on. Mathematical techniques which are used for this include mathematical analysis, linear algebra, stochastic analysis, differential equations, and measure-theoretic probability theory.

The initial analysis of the data from properly randomized studies often follows the study protocol. The data from a randomized study can be analyzed to consider secondary hypotheses or to suggest new ideas. A secondary analysis of the data from a planned study uses tools from data analysis.

While the tools of data analysis work best on data from randomized studies, they are also applied to other kinds of data --- for example, from natural experiments and observational studies, in which case the inference is dependent on the model chosen by the statistician, and so subjective. More complex experiments, such as those involving stochastic processes defined in continuous time, may demand the use of more general probability measures.

A probability distribution can either be univariate or multivariate. Important and commonly encountered univariate probability distributions include the binomial distribution, the hypergeometric distribution, and the normal distribution. The multivariate normal distribution is a commonly encountered multivariate distribution. Statistical inference is the process of drawing conclusions from data that are subject to random variation, for example, observational errors or sampling variation.

Inferential statistics are used to test hypotheses and make estimations using sample data. Whereas descriptive statistics describe a sample, inferential statistics infer predictions about a larger population that the sample represents. The outcome of statistical inference may be an answer to the question "what should be done next.

For the most part, statistical inference makes propositions about populations, using data drawn from the population of interest via some form of random sampling.

More generally, data about a random process is obtained from its observed behavior during a finite period of time.

Given a parameter or hypothesis about which one wishes to make inference, statistical inference most often uses:In statistics, regression analysis is a statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables.

More specifically, regression analysis helps one understand how the typical value of the dependent variable (or 'criterion variable') changes when any one of the independent variables is varied, while the other independent variables are held fixed. Less commonly, the focus is on a quantile, or other location parameter of the conditional distribution of the dependent variable given the independent variables.
