Thurstone Box Data

Description

Factor loading matrix derived from Thurstone's box data.

Usage

  data(Thurstone)

Format

A numeric matrix:

• box26: 26 x 3 matrix of unrotated factor loadings.

Details

Loading the data makes the following object available:

box26 is a 26 \times 3 unrotated factor loading matrix for 26 variables measured on a set of boxes. It appears frequently in the rotation literature as a dataset for comparing rotation criteria, particularly for assessing local minima.

The matrix is suitable as input to GPForth, GPFoblq, and all rotation wrapper functions in GPArotation. For a richer collection of factor analysis datasets, see the psych package.
