** I am not a statistician, but... The default arguments are: onet.permutation(x, nsim=2000, plotit=TRUE)
you are making nsim=4 (this parameter is not the size of each sample, it is the number of samples taken) You are building the distribution for a statistical test through random sampling, so you want to have MANY MANY random samples, not just 4. song_gpqg wrote: > > I saw the manual of this function but not sure what to do. > I have a array contain 7 numbers and want to choose 4 to do permutation > test.
