Data generated sampling from a multivariate normal distribution using as parameters \(samp\) = 150, \(es\) = 1.0,\(J\) = 20,\(rho\) = 0 where samp is the sample size, es is the effect size, J is the number os covariates, and rho is the correlation between pairs of covariates. The treatment condition (A) is sampled from a binomial distribution with \(p\) = 0.5 and the treatment outcome (Y) is obtained using the following regression \( Y = 1 + (.25 x X1) + (.25 x X2) - (.25 x X5]) - (es x ((A - 1) ^ 2)) + error\) where the error is sampled from a standard normal distribution.
