Statistics with R Warning Here are the notes I took while discovering and using the statistical environment R. However, I do not claim any competence in the domains I tackle: I hope you will find those notes useful, but keep you eyes open -- errors and bad advice are still lurking in those pages... Should you want it, I have prepared a quick-and-dirty PDF version of this document. The old, French version is still available, in HTML or as a single file. You may also want all the code in this document. 1. This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 2.5 License.
Multivariate analysis of variance Multivariate analysis of variance or multiple analysis of variance (MANOVA) is a statistical test procedure for comparing multivariate (population) means of several groups. Unlike univariate ANOVA, it uses the variance-covariance between variables in testing the statistical significance of the mean differences. It is a generalized form of univariate analysis of variance (ANOVA). It is used when there are two or more dependent variables. It helps to answer: 1. do changes in the independent variable(s) have significant effects on the dependent variables?; 2. what are the interactions among the dependent variables? Where sums of squares appear in univariate analysis of variance, in multivariate analysis of variance certain positive-definite matrices appear. Analogous to ANOVA, MANOVA is based on the product of model variance matrix, and inverse of the error variance matrix, , or . implies that the product The most common[3][4] statistics are summaries based on the roots (or eigenvalues) of the
Learning R R Programming - Wikibooks, collection of open-content textbooks Welcome to the R programming Wikibook This book is designed to be a practical guide to the R programming language[1]. R is free software designed for statistical computing. How can you share your R experience ? Explain the syntax of a commandCompare the different ways of performing each task using R.Try to make unique examples based on fake data (ie simulated data sets).As with any Wikibook please feel free to make corrections, expand explanations, and make additions where necessary. Some rules : Prerequisites[edit] We assume that readers have a background in statistics. We also assume that readers are familiar with computers and that they know how to use software with a command-line interface.

start [R Wiki] * R is a free software environment for statistical computing and graphics. It runs on a wide variety of UNIX platforms, Windows and MacOS. This R Wiki is dedicated to the collaborative writing of R documentation. For information on browsers, RSS syndication, copyright, ... read usage. R comes with several official manuals and FAQs. These should be your primary source of information. Personal note: I have some difficulties with the statement that the official manuals should be your primary source of information. Books I found ordinary books to be the most helpful source of information for novice programmers and I can particularly recommend: Adler, J. (2010) R in a nutshell. Help forum for programmers The R-Help mailing list can give excellent answers, but due to the high calibre of respondents it can be intimidating, (and off-putting). In addition I can’t but feel that many questions are a waste of time for most of those who respond. Stackoverflow

Statistics: Methods and Applications textbook offers training in the understanding and application of statistics and data mining. It covers a wide variety of applications, including laboratory research (biomedical, agricultural, etc.), business statistics, credit scoring, forecasting, social science statistics and survey research, data mining, engineering and quality control applications, and many others. The Textbook begins with an overview of the relevant elementary (pivotal) concepts and continues with a more in depth exploration of specific areas of statistics, organized by "modules", representing classes of analytic techniques.

Basic Widget Methods Widget (class) [#] Widget implementation class. This class is used as a mixin by all widget classes. after(delay_ms, callback=None, *args) [#] Registers an alarm callback that is called after a given time. This method registers a callback function that will be called after a given number of milliseconds. The callback is only called once for each call to this method. class App: def __init__(self, master): self.master = master self.poll() def poll(self): ... do something ... self.master.after(100, self.poll) after_cancel to cancel the callback. You can also omit the callback. delay_ms Delay, in milliseconds. callback The callback. *args Optional arguments that are passed to the callback. Returns: An alarm identifier. after_cancel(id) [#] Cancels an alarm callback. id Alarm identifier. after_idle(callback, *args) [#] Registers a callback that is called when the system is idle. bbox(column=None, row=None, col2=None, row2=None) [#] The bbox method. column row col2 row2 bell(displayof=0) [#] displayof cget(key) [#]
