To specify one or more scenarios for an analysis parameter (or set of parameters) in the POWER statement, you provide a list of values for the option that corresponds to the parameter(s). To identify the parameter you want to solve for, you place a missing value in the appropriate list.
There are three basic types of such lists: number-lists, name-lists, and keyword-lists. Scenarios for scalar-valued parameters, such as power, are represented by a number-list. Scenarios for named parameters, such as correlation matrices, are represented by a name-list. Some parameters, such as the test statistic for a multivariate model, have values that are represented by one or more keywords in a keyword-list.
