Applied psychometrics

All material presented in the course is available to download on this page. No additional resources are necessary, unless you want to go your way beyond what is being covered during the classes.
Remark. As a general advice, always try to work with the latest R version (currently, 2.10.1, 2009-12-14), read the R news and save all your commands in dedicated text file(s); also don't forget to save your R workspace when you're done.

These are draft chapters of forthcoming tutorials in Psychometrics (targeting a broad audience, including practicians as well as statisticians).
See History details to see how it evolves.
