GDA Syntax - Example 1: Simple Standard Discriminant Analysis

This example illustrates the specifications for a simple discriminant analysis problem, with continuous predictor variables. Note that brief descriptive comments are enclosed in curly brackets. You can run this example with the example data file Irisdat.sta.

GDA;

{ Dependent variable; no codes (values) are specified, so STATISTICA will by default take all 3 grouping codes in variable Iristype: }

DEPENDENT = IRISTYPE;

{ Specification of continuous predictor variables }

COVARIATE = SEPALLEN SEPALWID PETALLEN PETALWID;

{ Analysis design }

DESIGN = SEPALLEN + SEPALWID + PETALLEN + PETALWID;
