The POWER Procedure


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 language. For example, for the one-sample t test you can specify four scenarios (30, 50, 70, and 100) for a total sample size in any 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 as follows:

   NTOTAL = .
