HOMALS (homogeneity analysis by means of alternating least squares) estimates category
quantifications, object scores, and other associated statistics that separate categories (levels)
of nominal variables as much as possible and divide cases into homogeneous subgroups.
Data and variable selection. You can use a subset of the variables in the analysis and restrict
the analysis to the first n observations.
Number of dimensions. You can specify how many dimensions HOMALS should compute.
Iterations and convergence. You can specify the maximum number of iterations and the value
of a convergence criterion.
Display output. The output can include all available statistics, just the default frequencies,
eigenvalues, discrimination measures and category quantifications, or just the specific statistics
you request. You can also control which statistics are plotted and specify the number
of characters used in plot labels.
