Dear Joe,
Perfect, that was incredibly helpful.
The only problem is that, I want to count the mean age at which the
first cancer test was conducted. For that I need in this variable only
one age per patientid (in the row where the first exam was conducted).
The same goes to number of days for which there was a cancer exam,
only one number per patientid (in any row)
Once again thank you
Kind Regards,
John
