I was indeed thinking that, thanks.
Now, I am able to find the maximum per individual, using
by each_individual: sum probability, meanonly
I'd like to save the maximum value of each individual in some variable. So:
individual value max
1 .4 .6
1 .6 .6
2 .35 .65
2 .65 .65
etc.
How do I save those maximum values per individual in a new variable?
Cheers, Peter
