Is it possible to observe the sum of a set of random variables, and if so, how would it be done? I know I can use
tt.sum in a variable’s properties, like this for example:
But let’s say I have a population and I observe the mean, instead of actual individual measures. I know I can read the mean out of a trace as follows:
But how could I add an observation of the value of mu? I know I can’t observe an arbitrary
Deterministic RV, but it seems like I should be able to observe a sum?
Oh, yes, if it helps, I would be observing both the mean and the standard deviation of these populations.
