Centre for Multilevel Modelling | MLwiN
A software package for fitting multilevel models A few of its features Names window (where you can see all the variables) Equations window (showing what model has been fitted and the parameter estimates). More >> Variance function window (to calculate the residual variance at any level) Predictions window (to calculate predicted values for each individual in the dataset, specifying what should be included in the prediction), and Graphs (here the user has selected the country line that seems to be different from the others and asked that points relating to this country be drawn in red in all graphs, to help in deciding whether this is an outlier; the country is the Netherlands, as the user would have seen when they clicked on the line).

Survey analysis in R
This is the homepage for the "survey" package, which provides facilities in R for analyzing data from complex surveys. The current version is 3.29. A much earlier version (2.2) was published in Journal of Statistical Software
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.

Outils.Stat a été développé dans le but de proposer une interface permettant l'utilisation de R depuis Microsoft Excel(c). Il repose sur les développements de R, Rexcel et RCom. Conçu à l'origine pour offrir aux étudiants en psychologie un outil simple et gratuit complètement intégré au tableur, il offre également des possibilités susceptibles d'intéresser les enseignants chercheurs.

Naomi Robbins, a consultant and seminar leader who specializes in the graphical display of data, offers training on the effective presentation of data. She also reviews documents and presentations for clients. She is the author of Creating More Effective Graphs . Three common challenges statisticians and others face when preparing data for presentation include poor options and defaults in many software packages used for creating graphs, managers and colleagues who are socialized to expect figures that attract attention, and poor instructions from conference organizers. This article addresses each of these challenges and offers some tips for dealing with them.
Visualizing Data: Challenges to Presentation of Quality Graphics—and Solutions
Microsoft Excel Spreadsheets We have created the following spreadsheets to assist in statistical calculations. Each spreadsheet is "protected" so that it will only let you type in certain cells so that you don't accidentally overwrite any important formulas.

So far we have been plotting frequencies. An advantage barplot() has over plot() is that you can get the height of bars to represent any measure you like. Below I use tapply() to get the means of q1 by gender, store it in myMeans and then plot those means.

The Likert Question Question | Data Revelations
Overview I’ve been looking at various examples over at Stephen Few’s Perpetual Edge web site and one example ( this one ) really resonates with me as it deals with how to visualize Likert Scale questions. For the past five years I’ve used Tableau to analyze literally thousands of survey questions, but I’ve never really been happy with how I presented Likert Scale questions results. That said, a new version of Tableau has brought new capabilities…Introduction à R - Alea
Ce document a pour objectif de présenter l'utilisation de R a des étudiants ou chercheurs en sciences sociales, et plus généralement à des personnes n'ayant pas forcément une grosse expérience en informatique. Le document est disponible en version PDF. Le code source Sweave est également téléchargeable, mais il ne contient pas les captures d'écran et autres images non générées par R. Ce document est étroitement lié à l'extension rgrs , également présentée et décrite sur ce site. Par ailleurs, si vous souhaitez échanger ou obtenir de l'aide sur l'utilisation de R en sciences sociales, n'hésitez pas à rejoindre et à solliciter la liste de discussion R-soc dédiée à ce sujet.StatSpss
