Unstandardizing coefficients in order to interpret them on the original scale is often necessary when explanatory variables were standardized to help with model convergence when fitting generalized linear mixed models. Here I show one automated approach to unstandardize coefficients from a generalized linear mixed model fit with lme4.
I currently work as an applied statistician in aviation and aeronautics. In a previous role as a consulting statistician in academia I created and taught R workshops for applied science graduate students who are just getting started in R, where my goal was to make their transition to a programming language as smooth as possible. See these workshop materials at my website.
