Simulated data
Description
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.
