Hi,
Although my question is not directly linked to R functionality, I hope
you can forgive me for posing it here. I have been looking for the
answer for a long time (~ 4 weeks) and have not been able to find it. My
question is:
Suppose I have an m*n matrix, with a random (normally distributed)
What do you think about the following:
library(nlme)
set.seed(1)
n - 3;m - 4
s.e - 0
(X0 - array(rep(rnorm(n), each=m)+s.e*rnorm(m*n),
dim=c(m, n)))
s.e - 1
(X1 - array(rep(rnorm(n), each=m)+s.e*rnorm(m*n),
dim=c(m, n)))
X. - data.frame(Row=as.vector(row(X)),
Hi,
Can anyone help me with the following (although not directly correlated
to R functionality)? I have been looking on the internet but can not
find the answer.
My question: what is the variation on the mean of a limited distribution
(total N points normally distributed), when I have a small
Ehh, by limited distribution, I meant to say a population of N points.

Hi,
Can
If the sample is drawn with replacement from the finite population, then the
usual formula applies (assuming iid samples); i.e., var(sample mean) =
var(population) / n.
There's some problem in your description: A finite population, I believe,
is necessarily discrete (since there are only N
be it...
