class RPsych(RPackage):
"""A general purpose toolbox for personality, psychometric theory and
experimental psychology. Functions are primarily for multivariate
analysis and scale construction using factor analysis, principal
component analysis, cluster analysis and reliability analysis, although
others provide basic descriptive statistics. Item Response Theory is
done using factor analysis of tetrachoric and polychoric correlations.
Functions for analyzing data at multiple levels include within and
between group statistics, including correlations and factor analysis.
Functions for simulating and testing particular item and test structures
are included. Several functions serve as a useful front end for
structural equation modeling. Graphical displays of path diagrams,
factor analysis and structural equation models are created using basic
graphics. Some of the functions are written to support a book on
psychometric theory as well as publications in personality research.
For more information, see the <http://personality-project.org/r> web
page."""
