I have a dataset of 10 variables and 5000 observations. I need to calculate
the median of each variable in groups of 30 observations, i.e., the median
of each variable in observations 1-30, then the median for 31-60, then
61-90, etc. I know I can get the median from the p50 value of -summarize-,
but I'm not sure how to obtain consecutive segments of 30 observations each
to perform -summarize- on. Can anyone help?
Thanks, Morry Hodges
