Calculate PRE from Cohen's f, f_squared, or partial correlation

Description

Calculate PRE from Cohen's f, f_squared, or partial correlation

Usage

calc_PRE(f = NULL, f_squared = NULL, r_p = NULL)

Arguments

f	Cohen's f. Cohen (1988) suggested >=0.1, >=0.25, and >=0.40 as cut-off values of f for small, medium, and large effect sizes, respectively.
f_squared	Cohen's f_squared. Cohen (1988) suggested >=0.02, >=0.15, and >=0.35 as cut-off values of f for small, medium, and large effect sizes, respectively.
r_p	Partial correlation.

Value

A list including PRE, the absolute value of r_p (partial correlation), Cohen's f_squared, and f.
