Gorsuch: Example data set from Gorsuch (1997) for an example factor extension.

Description

Gorsuch (1997) suggests an alternative to the classic Dwyer (1937) factor extension technique. This data set is taken from that article. Useful for comparing link{fa.extension} with and without the correct=TRUE option.

Usage

data(Gorsuch)

Arguments

Details

Gorsuc (1997) suggested an alternative model for factor extension. His method is appropriate for the case of repeated variables. This is handled in link{fa.extension} with correct=FALSE
