The GLMPOWER Procedure
Number-Lists
A number-list can be one of two things: a series of one or more numbers expressed in the form of one or more DOLISTs, or a missing value indicator ( . ).
The DOLIST format is the same as in the DATA step. For example, you can specify four scenarios (30, 50, 70, and 100) for a total sample size in either of the following ways:
NTOTAL = 30 50 70 100 NTOTAL = 30 to 70 by 20 100
A missing value identifies a parameter as the result parameter; it is valid only with options representing parameters you can solve for in a given analysis. For example, you can request a solution for NTOTAL:
NTOTAL = .
