Dear Statalist,

this may sound like a very silly question. But I seem to be unable to solve it anyway.


My data looks like this:

id x
1 5
1 5
1 10
1 10
1 21
1 21
1 21
2 ...

I want to generate a newvar with the maximum value of x , which is _N. But if the difference between the largest and the second largest value is <=7, newvar should take the value of the second largest value of x.

Any suggestions on this?

Cheers
Hans
