Question about biasing in sd()???
Hi,
Can anyone help me with the following. I have been using R for Monte
Carlo simulations and got some results I couldn't explain. Therefor I
performed following short test:
--------------
mean.sds <- NULL
sample.sizes <- 3:30
for(N in sample.sizes){
dum <- NULL
for(I in 1:5000){
x <- rnorm(N,0,1)
dum <- c(dum,sd(x))
}
mean.sds<- c(mean.sds,mean(dum))
}
