In medmod: Simple Mediation and Moderation Analysis

medmod 1.2.0

New features

• Both analyses can now display a path diagram of the fitted model, with optional path labels, coefficient estimates and significance stars. The moderation diagram optionally draws the moderator's main-effect path.
• The moderation estimates table can now display coefficient labels matching the simple slope parametrisation.
• Model estimates are cached, so changing display options no longer refits the model (particularly noticeable with bootstrap standard errors).
• Added two example datasets to jamovi's data library, one for mediation and one for moderation.

Bug fixes

• Results now correctly refresh when the confidence level or the number of bootstrap samples changes.
• The percent mediation column now uses the same estimates as the other columns (no change in results for these models, where the two coincide).
• Replaced deprecated ggplot2 idioms (aes_string(), size for line widths).
• Analyses now give an informative error when an expected model term is missing from the estimates.

medmod 1.1.0

• Releases prior to 1.2.0 were not documented here.
