Hey
I want to create an index out of 10 variables, each of them has values on a scale from 1 to 5.
I know that I have to use:
gen index = (AC+AD+AE+AF+AG+AH+AI+AJ+AK+AL), but I guess that`s not complete, or is it?
I found an old dofile with an index (other variables) I created two years ago with was: generate index = ((V50+V51+V52+V53)-4)/12
So i guess I also have to substract and divide by some number. I was trying to derive the numbers from the old index I found, but I really have no idea what numbers I have to choose.
Can someone possibly help me with this? That would be amazing
Best wishes
Katja
