Questions tagged [psych]

An R package for analysing personality, psychometrics and experimental psychology. Do not use this tag for Ruby standard library Psych.

psych is an package containing functions for analysing personality, psychometrics and experimental psychology. Functions are primarily for scale construction using factor analysis, and analysis, although others provide basic descriptive statistics. Item Response Theory is done using factor analysis of tetrachoric and polychoric s. Functions for simulating particular item and test structures are included. Several functions serve as a useful front end for structural equation modeling. Graphical displays of path diagrams, and structural equation models are created using basic graphics.
