You are studying psychology, business administration or some other social science and are looking for information about statistical methods?

I have specialized in moderation, mediation and moderated mediation analyses for which I mostly use the PROCESS macro by A. Hayes (with versions for SPSS and for R), and in SEM, CFA and path analysis with the lavaan package in R.

Here you can find my statistics tutorials about moderation & mediation and other topics of multivariate statistics. And my consulting services for students (moderated mediation with PROCESS; SEM, CFA, path analysis with lavaan; multilevel models with R).
