# Create an example data matrix with 50 observations that contains an ID variable for every unit, a dummy variable indicating gender, an age variable (between 18 and 55), a treatment variable and an outcome variable (between 15 and 20).

id <- seq(1,50,1)
gender <- sample(c(1,2), 50, replace=T)
age <- sample(seq(18,55,1), 50, replace=T)
