hello, I?ve got a problem: I have two samples x <- rnorm(30, 0,1) y <- rnorm(30,0.1,1) and i want to test the equality of them. Here i've got a problem: w <- c(x, y) r <- bootstrap(w,100, mean) # from the bootstrap package and save the values r$thetastar But i do H0: Fx=Fy so i create w and after this i wish to separate the bootstraped values of w into two new population xb e yb and in this values calculate the mean. How i do that? thanks & sorow by my english Rafael Bertola Undergraduate in Statistics at UNICAMP - Brasil -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
