gtheoryr: Simple Generalizability Theory for Crossed and Nested Designs

Provides a small, beginner-friendly interface for estimating variance components in simple generalizability theory designs. The package currently supports a fully crossed persons-by-items design, generic balanced crossed designs with one or more additional facets such as raters, occasions, or forms, and a simple items-within-person nested design, along with design-study summaries for relative and absolute decisions. Includes data diagnostics, measurement error intervals, design comparison and cost planning, sensitivity analysis, Gaussian simulation and parametric bootstrap uncertainty estimates for balanced crossed designs.
