Simple Mediation and Moderation Analysis R package medmod version 1.2.0 This toolbox allows you to do simple mediation and moderation analysis. Models are estimated with the 'lavaan' package by Rosseel (2012) <doi:10.18637/jss.v048.i02>; standard errors for the mediation estimates are computed with the delta method following Sobel (1982) <doi:10.2307/270723> or by bootstrapping. It is also available as a module for 'jamovi' (see <https://www.jamovi.org> for more information). You can find an in depth tutorial on the 'lavaan' model syntax used for this package on <https://lavaan.ugent.be/tutorial/index.html>.
