Displaying 1 result from an estimated 1 matches for "max_exposure".

Selecting Variables
...and then for these count the entries
across each case i.e
ID Exposure_1 Exposure_2 Exposure_3
1 y y y
2 y y -
3 y - -
So the corresponding new variables that would be created are
ID Max_Exposure Unique_Exposure
1 3 3
2 3 2
3 3 1
I know this may seem fairly basic but it will give me the starting point to
develop more advanced things with loop and nat lang
Thanks in advance
Mike
