Thank you for your help, but the number of measurement is different from
patient to patient. So I need to get the maximum value of measurement:
egen max_mes=max(nb_mes)
And then use
forvalues i=1/`max_mes' {
...
----------------------------------------------
No; -forvalues- needs a constant. If you know that
the patient with most measurements has 97 measurements,
the command is:
forvalues i=2/97 {
For all patients this creates the variables diff2-diff97,
but for the patient with three measurements, diff4-diff92
have missing values. And that is how it should be.
Hope this helps
