ANALYSIS Subcommand (DISCRIMINANT command)

ANALYSIS is used to request several different discriminant analyses using the same grouping variable, or to control the order in which variables are entered into a stepwise analysis.

  • ANALYSIS is optional for the first analysis block. By default, all variables specified on the VARIABLES subcommand are included in the analysis.
  • The variables named on ANALYSIS must first be specified on the VARIABLES subcommand.
  • The keyword ALL includes all variables on the VARIABLES subcommand.
  • If the keyword TO is used to specify a list of variables on an ANALYSIS subcommand, it refers to the order of variables on the VARIABLES subcommand, which is not necessarily the order of variables in the active dataset.

Example

DISCRIMINANT GROUPS=SUCCESS(0,1)
  /VARIABLES=V10 TO V15, AGE, V5
  /ANALYSIS=V15 TO V5
  /ANALYSIS=ALL.
  • The first analysis will use the variables V15, AGE, and V5 to discriminate between cases where SUCCESS equals 0 and SUCCESS equals 1.
  • The second analysis will use all variables named on the VARIABLES subcommand.
