POWER UNIVARIATE LINEAR

POWER UNIVARIATE LINEAR is available in IBM® SPSS® Statistics Base Edition. The command invokes power analysis for the type III F-test in univariate linear regression. Univariate linear regression is a basic and standard statistical approach in which researchers use the values of several variables to explain or predict values of a scale outcome.
