InteractionPoweR 0.2.2
- 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()andpower_interaction_r2_covs(). - Minor bug fixes.
- Removes dependency on the {MASS} package.
InteractionPoweR 0.2.1
CRAN release: 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.
InteractionPoweR 0.2.0
CRAN release: 2022-10-20
- Removes options for specifying skew, which contained a bug.
- Also a speed-up for the simulations.
InteractionPoweR 0.1.0.6
- Added
power_interaction_r2()function for analytic power.
InteractionPoweR 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.
