Changes in version 0.2.4 (2026-03-24) - Adds citation information and minor bug fixes. Changes in version 0.2.3 - Adds two-way interaction stability function - run_pos_power_search(). Changes in version 0.2.2 (2024-07-09) - Adds power analysis function for 3-way interactions - power_interaction_3way_r2(). - Adds convenience function for visualizing the correlation matrix from a 3-way interaction - cor.mat.3way(). - Adds convenience function for visualizing the simple slopes from a 3-way interaction - simple.slopes.3way(). - Adds power analysis function for 2-way interactions with covariates - generate.interaction.cov.input() and power_interaction_r2_covs(). - Minor bug fixes. - Removes dependency on the {MASS} package. Changes in version 0.2.1 (2023-04-18) - Fix bug in power_interaction_r2() which effected analyses with a high ‘r.x1.x2’ correlation. - Fix warning in plot_interaction(). - Adds additional descriptive error messages. Changes in version 0.2.0 (2022-10-20) - Removes options for specifying skew, which contained a bug. - Also a speed-up for the simulations. Changes in version 0.1.1 (2022-08-24) - First CRAN release. Changes in version 0.1.0.6 - Added power_interaction_r2() function for analytic power. Changes in version 0.1.0.5 - Adds options to simulate ordinal variables (e.g., a likert scale) in power_interaction() using the ‘k.x1’, ‘k.x2’, and ‘k.y’ options. - Also a speed-up and minor bug-fixes.
