8M – Boolean Factor Analysis

Boolean Factor Analysis using BMDP Statistical Software Program 8M

8M estimates Boolean factors of dichotomous (binary) data. In this analysis, the arithmetic used in matrix multiplication is Boolean, so the factor scores and loadings are binary. In 4M, the scores from an analysis of binary data are linear combinations of the data. In 8M, a case has a score of 1 if it has a positive response for any of the variables dominant in the factor and zero otherwise.
