Utility Functions for Exploratory Factor Analysis

A number of utility function for exploratory factor analysis are included in this package. In particular, it computes standard errors for parameter estimates and factor correlations under a variety of conditions.


The goal of EFAutilities is to provide a number of utilities functions for exploartory factor analysis. In particular, it computes standard errors for model parameters under a variety of conditions.

This package can be installed directly from CRAN:

install.packages("EFAutilities") library(EFAutilities)

Example

Examples using the data sets included in the packages:

data("CPAI537") # Chinese personality assessment inventory (N = 537)

efa(x=CPAI537,factors=4, fm='ml') # normal, ml, oblique, CF-varimax, information, merror='NO'

...
