avoiding loop
...trying to figure out a way to improve my code's efficiency by avoiding the use of loop.
I want to calculate a conditional mean(?) given time.
For example, from the data below, I want to calculate sum((value|choice==1)/sum(value)) across time.
Is there a way to do it without using a loop?
