    Why between-group effects estimating in MLMs are sometimes biased, and what to do about it

    My advisor told me I should group-mean center my predictors in my multilevel model because it might “make my effects significant” but this doesn’t seem right to me. What exactly is involved in centering predictors within the multilevel model?

    A reviewer recently asked me to comment on the issue of equivalent models in my structural equation model. What is the difference between alternative models and equivalent models within an SEM?

    An equivalent model can be thought of as a re-parameterization of the original model. In other words, it is just a different way of “packaging” th…
