%description
Miscellaneous functions and data used in psychological research and
teaching. Keng currently has a built-in dataset depress, and could (1)
scale a vector; (2) compute the cut-off values of Pearson's r with known
sample size; (3) test the significance and compute the post-hoc power for
Pearson's r with known sample size; (4) conduct prior power analysis and
plan the sample size for Pearson's r; (5) compare lm()'s fitted outputs
using R-squared, f_squared, post-hoc power, and PRE (Proportional
Reduction in Error, also called partial R-squared or partial Eta-squared);
(6) calculate PRE from partial correlation, Cohen's f, or f_squared; (7)
conduct prior power analysis and plan the sample size for one or a set of
predictors in regression analysis; (8) conduct post-hoc power analysis for
one or a set of predictors in regression analysis with known sample size.
