I want to do a calculation like this $\max_{a \in A} \sum_{s \in S} g(s, a)$. Of course, I can do something like this: maximum([sum([g(s, a) for s in S]) for a in A]) But it seems like it would be nicer to have the s in S and a in A go in front like in the written equation. I'd like something l

No problem. Honestly, I'm not sure formula is a useful way to think about regression, the formula is uniquely determined from: (depVar, indepVars, data, family, link) so that the + symbols are redundant given family and link, glm(Y ~ X1 + X2 + X3 + X4 + X5 +, family, link) and it would be n
