A list will be returned with the following named values: var - the projected variable delta, tau - intermediate variables
hhid <- c("a","b","c","a","b","c" ,"a","b","c" ,"a","b","c" ,"a","b","c") tid <- c("1","1" ,"1" ,"2","2" ,"3","3","3" ,"4","4","5" ,"5","6","6" ,"6") w <- rep(1, 15) x1 <- rnorm(15, mean=50, sd=10) struc <- projdummies(hhid, tid, w) x1p <- projvar(x1, struc)
