Assigning Data to Roles

To run the Discriminant Analysis task, you must select an input data source and assign a variable to the Group variable role. To filter the input data source, click Filter Icon.
Roles
Description
Roles
Group variable
specifies the group variable for the discriminant analysis.
To specify the prior probabilities of group membership, click Priors. By default, the prior probabilities are equal.
Quantitative variables
specifies the quantitative variables to use in the analysis.
Additional Roles
Frequency count
lists a numeric variable whose value represents the frequency of the observation. If you assign a variable to this role, the task assumes that each observation represents n observations, where n is the value of the frequency variable. If n is not an integer, SAS truncates it. If n is less than 1 or is missing, the observation is excluded from the analysis. The sum of the frequency variable represents the total number of observations.
Weight
lists the relative weight for each observation in the data source.
Group analysis by
enables you to obtain separate analyses of observations for each unique group.
