Hello. I have a question about a step in the factorization theorem demonstration.
1. Homework Statement
Here is the theorem (begins end of page 1), it is not my course but I have almost the same demonstration : http://math.arizona.edu/~jwatkins/sufficiency.pdf
Screenshot of it:
Could someone please explain me how to justify the first equality of that step?
I think a possible justification is because the sample is a sufficient statistic but it feels like it's not enough/not the right justification
