Dear All,

I have repeated measures of the same observational units; specifically, for each observational unit, there are 6 measurements.

From these six measurements, I need to randomly select one measurement for each person.

For example, if there were 100 persons measured six times, there would be 600 measurements. From these 600 measurement, I would need 100 measurements, but each person should only be sampled once.

Say "person" is numbered from 1 to 100, and "measurements" is numbered from 1 to 6. Which sytnax could I use to make the kind of selection outlined above? Many thanks for your help!
