480 DISCRIMINANT<br />

RAW Unstandardized canonical discriminant functions.<br />

COEFF Classification function coefficients. Although DISCRIMINANT does not<br />

directly use these coefficients to classify cases, you can use them to classify<br />

other samples (see the CLASSIFY subcommand below).<br />

TABLE Classification results. If both selected and unselected cases are classified, the<br />

results are reported separately. To obtain cross-validated results for selected<br />

cases, specify CROSSVALID.<br />

CROSSVALID Cross-validated classification results. The cross-validation is done by treating<br />

n–1 out of n observations as the training data set to determine the discrimination<br />

rule and using the rule to classify the one observation left out. The<br />

results are displayed only for selected cases.<br />

ALL All optional statistics.<br />

ROTATE Subcommand<br />

The coefficient and correlation matrices can be rotated to facilitate interpretation of results.<br />

To control varimax rotation, use the ROTATE subcommand.<br />

• Neither COEFF nor STRUCTURE affects the classification of cases.<br />

COEFF Rotate pattern matrix. DISCRIMINANT displays a varimax transformation<br />

matrix, a rotated standardized canonical discriminant function coefficients<br />

table, and a correlations between variables and rotated functions table.<br />

STRUCTURE Rotate structure matrix. DISCRIMINANT displays a varimax transformation<br />

matrix, a rotated structure matrix, and a rotated standardized canonical<br />

discriminant function coefficients table.<br />

NONE Do not rotate. This is the default.<br />

HISTORY Subcommand<br />

HISTORY controls the display of stepwise and summary output.<br />

• By default, HISTORY displays both the step-by-step output and the summary table<br />

(keyword STEP, alias END).<br />

STEP Display step-by-step and summary output. Alias END. This is the default. See<br />

Stepwise statistics in “STATISTICS Subcommand” on p. 479.<br />

NONE Suppress the step-by-step and summary table. Alias NOSTEP, NOEND.<br />

CLASSIFY Subcommand<br />

CLASSIFY determines how cases are handled during classification.<br />

• By default, all cases with nonmissing values for all predictors are classified, and the<br />

pooled within-groups covariance matrix is used to classify cases.
