(description
|
||||
"This package provides 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.")
