Hi,
I have a data set that has about 15,000 data points (rows) that document
values of 15 variables (columns). Now I'd like to perform a random sampling
process (run 10,000 times) to randomly select 470 points and get the mean
values of my 15 variables (columns) out of these 470 points after the 10,000
times of random sampling. Can anyone tell me how to write a script in SAS,
SYSTAT, R or S-Plus to perform this analysis? Or are there other methods I can
use? Thanks a lot! Ophelia
