performance is part of the easystats ecosystem and offers model quality assessment tools for R. It computes metrics like R², RMSE, ICC, and conducts diagnostics such as overdispersion, zero‑inflation, convergence, and singularity checks, complementing model workflows with comprehensive evaluation.

Features

  • Computes R², RMSE, ICC and other model indices
  • Diagnostic checks: convergence, zero-inflation, overdispersion
  • check_model() for automated multi-test visual summary
  • Works with linear, mixed‑effect, generalized, and Bayesian models
  • Integration with tidymodels and model objects from common packages
  • Lightweight and part of easystats with consistent API
