wp.mc.t: Power analysis for t-test based on Monte Carlo simulation

Description

Power analysis for t-test based on Monte Carlo simulation

Usage

wp.mc.t(n = NULL, R0 = 1e+05, R1 = 1000, mu0 = 0, mu1 = 0, 
sd = 1, skewness = 0, kurtosis = 3, alpha = 0.05, 
type = c("two.sample", "one.sample", "paired"), 
alternative = c("two.sided", "less", "greater"))
