Statistical Power With Respect To True Sample And True Population Paths: A Pls-Based Sem Illustration, Ned Kock, Murad Moqbel

Information Systems Faculty Publications

Monte Carlo experiments aimed at assessing the statistical power of structural equation modelling (SEM) techniques typically focus on true population path coefficients, ignoring true sample path coefficients. We demonstrate the limitations stemming from such practice in statistical power assessments. This is done in the context of SEM techniques employing the partial least squares (PLS) method, where power claims have led to much recent debate. We show that the sample sizes at which power is greater than .8 differ significantly when we consider true population and true sample paths, and that the difference increases with decreases in the magnitudes of the …
