SimData_1 {quint}R Documentation

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.
