General Discriminant Analysis (GDA) Models Startup Panel

Ribbon bar. Select the Statistics tab. In the Advanced/Multivariate group, click Mult/Exploratory and from the menu, select General Discriminant to display the General Discriminant Analysis (GDA) Models Startup Panel.

Classic menus. On the Statistics - Multivariate Exploratory Techniques submenu, select General Discriminant Analysis Models  to display the General Discriminant Analysis (GDA) Models Startup Panel.

The Startup Panel contains one tab: Quick. Use the options on this tab to select the Type of analysis and Specification method.

Element Name Description
OK Click the OK button to display the appropriate analysis specification dialog box, depending on the Specification method selected on the Quick tab.
Cancel Click the Cancel button to close the Startup Panel without performing an analysis.
Options See Options Menu for descriptions of the commands on this menu.
Open Data Click the Open Data button to display the Select Data Source dialog box, which contains options to choose the spreadsheet on which to perform the analysis. The Select Data Source dialog box contains a list of the spreadsheets that are currently active.
Select Cases Click the Select Cases button to display the Analysis/Graph Case Selection Conditions dialog box, which contains options to create conditions for which cases will be included (or excluded) in the current analysis. More information is available in the case selection conditions overview, syntax summary, and dialog description.
W Click the W (Weight) button to display the Analysis/Graph Case Weights dialog box, which contains options to adjust the contribution of individual cases to the outcome of the current analysis by "weighting" those cases in proportion to the values of a selected variable.
Weighted moments Select the Weighted moments check box to specify that each observation contributes the weighting variable's value for that observation. The weight values need not be integers. This module can use fractional case weights in most computations. Some other modules use case weights as integer case multipliers or frequency values. This option will only be available after you have defined a weight variable via the W option (see above).
DF = W-1 / N-1 When the Weighted moments check box is selected, moment statistics (e.g., mean, variance) can be based on the sum of the weight values for the weighting variable (W-1), or on the number of (unweighted) observations (N-1). The sums of squares and cross products will always be based on the weighted values of the respective observations. However, in computations requiring the degrees of freedom (e.g., standard deviation, ANOVA tables), the value for the degrees of freedom can either be computed based on the sum of the weight values, or based on the number of observations. Moment statistics are based on the sum of the weight values for the weighting variable if the W-1 option button is selected, and are based on the number of (unweighted) observations if the N-1 options button is selected.
