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
