The GLMPOWER Procedure
| PROC GLMPOWER Statement |
The PROC GLMPOWER statement invokes the GLMPOWER procedure. You can specify the following options.
- DATA=SAS-data-set
names a SAS data set to be used as the exemplary data set, which is an artificial data set constructed to represent the intended sampling design and the conjectured response means for the underlying population.
- ORDER=DATA | FORMATTED | FREQ | INTERNAL
-
specifies the order in which to sort the levels of the classification variables (which are specified in the CLASS statement).
This option applies to the levels for all classification variables, except when you use the (default) ORDER=FORMATTED option with numeric classification variables that have no explicit format. With this option, the levels of such variables are ordered by their internal value.
The ORDER= option can take the following values:
Value of ORDER=
Levels Sorted By
DATA
Order of appearance in the input data set
FORMATTED
External formatted value, except for numeric variables with no explicit format, which are sorted by their unformatted (internal) value
FREQ
Descending frequency count; levels with the most observations come first in the order
INTERNAL
Unformatted value
By default, ORDER=FORMATTED. For ORDER=FORMATTED and ORDER=INTERNAL, the sort order is machine-dependent.
For more information about sorting order, see the chapter on the SORT procedure in the Base SAS Procedures Guide and the discussion of BY-group processing in SAS Language Reference: Concepts.
- PLOTONLY
specifies that only graphical results from the PLOT statement be produced.
