Assigning Data to Roles

To run the Factor Analysis task, you must select an input data source. To filter the input data source, click Filter Icon

You must assign a variable to the Analysis variables role.

Roles	Description
Roles
Analysis variables	specifies the numeric variables to analyze.
Additional Roles
Variables to partial out	specifies the variables that are used to partial out the variables in the analysis. You specify a partial variable when you want the analysis to be based on a partial correlation or covariance matrix.
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	specifies the relative weights for each observation in the input data set.
Group analysis by	enables you to obtain separate analyses of observations in groups that are defined by the BY variables.
