Hi,
How do I get the mean between observations in a longitudinal dataset?
I have the following:
ID Measurement
1 10.02
1 9.96
1 8.24
1 7.56
1 6.94
2 3.23
2 4.55
2 5.78
2 7.89
2 6.32
3 4.21
3 7.89
3 8.94
3 10.55
It is basically transforming the data from longitudinal to non-longitudinal.
Many thanks,
Have you tried PROC MEANS? SUMMARY or UNIVARIATE or SQL will also work.
