[This site is to be moved to http://animation.yihui.name!] The goal of this site it to illustrate various statistical concepts, computing processes and statistical data through the way of animations using R -- a language and environment for statistical computing and graphics, or, to put it short, "To make it interesting to learn and use statistical methods and do statistical analyses".
My examples will start from the basic theories of probability and mathematical statistics (CLT, estimation & hypothesis testing, etc), then go through classical linear models and nonparametric statistics, and finally be diversified into several directions such as time series, multivariate statistics, econometrics, numerical optimization, data mining and machine learning, etc. Here is a description about how to make animations.
My reason is extremely simple: because R is a language based on S for statistics. (Actually there are three reasons which I've marked in italic fonts!)
My name is Yihui XIE, and I'm just a little nobody studying in the School of Statistics, Renmin University of China. The coverage rate of my interests in the field of statistics is somewhat big currently, however, what I like most is to interprete the theories and outputs of statistical methods through the way of graphics (probably) because I always tend to think in a geometric way instead of an algebraic way.
