⚠️There's a newer version (3.0) of this package.Take me there.

LMERConvenienceFunctions (version 2.10)

Model Selection and Post-hoc Analysis for (G)LMER Models

Description

The main function of the package is to perform backward selection of fixed effects, forward fitting of the random effects, and post-hoc analysis using parallel capabilities. Other functionality includes the computation of ANOVAs with upper- or lower-bound p-values and R-squared values for each model term, model criticism plots, data trimming on model residuals, and data visualization. The data to run examples is contained in package LCF_data.
