CRAN Task View: Psychometric Models and Methods

Maintainer:Patrick Mair

Psychometrics is concerned with theory and techniques of psychological measurement. Psychometricians have also worked collaboratively with those in the field of statistics and quantitative methods to develop improved ways to organize, analyze, and scale corresponding data. Since much functionality is already contained in base R and there is considerable overlap between tools for psychometry and tools described in other views, particularly in SocialSciences, we only give a brief overview of packages that are closely related to psychometric methodology.

Please let me know if I have omitted something of importance, or if a new package or function should be mentioned here.
