https://info.5y1.org/compute-r-and-r2-calculator_1_3670d8.html
The R2 program (discussed below) is designed for correlation analysis (all variables are random). Under most circumstances you will get the similar results from R2 and G*Power. For example, suppose I ask how much power I would have for a large effect, alpha = .05,
