You must assign columns
to the Dependent variable and Classification
variable roles.

Roles
|
|
|
Dependent
variable
|
specifies the column
to use as the dependent variable.
|
|
Classification
variable
|
defines the subgroups.
Separate analyses are performed for each subgroup. You can specify
whether to treat missing values as a valid level.
|
|
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.

Group analysis

enables you to obtain separate
analyses of observations for each unique group.
