Factor Analysis Scores
Save as variables. Creates one new variable for each factor in the final solution.
Method. The alternative methods for calculating factor scores are regression, Bartlett, and Anderson-Rubin.
- Regression Method. A method for estimating factor score coefficients. The scores that are produced have a mean of 0 and a variance equal to the squared multiple correlation between the estimated factor scores and the true factor values. The scores may be correlated even when factors are orthogonal.
- Bartlett Scores. A method of estimating factor score coefficients. The scores that are produced have a mean of 0. The sum of squares of the unique factors over the range of variables is minimized.
- Anderson-Rubin Method. A method of estimating factor score coefficients; a modification of the Bartlett method which ensures orthogonality of the estimated factors. The scores that are produced have a mean of 0, have a standard deviation of 1, and are uncorrelated.
