pwranova - Power Analysis of Flexible ANOVA Designs and Related Tests
Provides functions for conducting power analysis in ANOVA
designs, including between-, within-, and mixed-factor designs,
with full support for both main effects and interactions. The
package allows calculation of statistical power, required total
sample size, significance level, and minimal detectable effect
sizes expressed as partial eta squared or Cohen's f for ANOVA
terms and planned contrasts. In addition, complementary
functions are included for common related tests such as t-tests
and correlation tests, making the package a convenient toolkit
for power analysis in experimental psychology and related
fields.
