JASP Regression module is a core module for JASP that provides tools for evaluating the association between variables. The Regression module offers a wide range of functionalities, including frequentist and Bayesian correlation, linear regression, logistic regression, and a generalized linear model.

The functionality is served by several R packages

• BAS — Bayesian variable selection and model averaging for linear models (BAS on CRAN)
• bstats — Bayesian statistics utilities (bstats on GitHub)
• emmeans — Estimated marginal means and contrasts (emmeans on CRAN)
• logistf — Firth's bias-reduced logistic regression (logistf on CRAN)
• ppcor — Partial and semi-partial correlation (ppcor on CRAN)
• VGAM — Vector generalized linear and additive models (VGAM on CRAN)
