MRC_all: Compute power for Multiple Regression with Up to Five...

In pwr2ppl: Power Analyses for Common Designs (Power to the People)

Compute power for Multiple Regression with Up to Five Predictors Requires correlations between all variables as sample size. Means, sds, and alpha are option. Also computes Power(All)

Description

Compute power for Multiple Regression with Up to Five Predictors Requires correlations between all variables as sample size. Means, sds, and alpha are option. Also computes Power(All)
