Roles
|
|
Row variables
|
specifies the row for
one-way table analysis. If multiple variables are assigned to this
role, the task performs multiple one-way table analyses.
|
Column variables
|
creates the columns
for one-way table analysis. If only column variables are assigned,
the task performs multiple one-way table analyses.
|
Strata variables
|
creates the separate
tables for n-way frequency and crosstabulation tables.
Note: You must assign columns to
both the Row variables or Column
variables roles to use a strata variable.
|
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.
