Abstract
A method for comparing completely standardized solutions in multiple groups is outlined. It is based on a correlation structure analysis of equal-size samples and uses the correlation distribution theory implemented in the program RAMONA. Unlike the common metric completely standardized solution, the approach yields parameter standard errors and can be applied to scale-invariant models as well as to models that do not exhibit this property. The method is illustrated on a 2-group cognitive aging data set from the Berlin Aging Study.
