How would one set that up on a statistical software like Stata? I hesitated trying it because I was worried about the difference in sample size. For instance consider the following: n1: 9th circuit court (20 reversals; 5 affirmations) n2: all other courts (100 reversals 9 affirmations) If I group all other courts into n2, will the difference in sample size matter? Also I would assume that there is no way to do this test using actual proportions (Rate of Reversals). Rather I would have to do it by breaking it down by Reversals vs. Affirmations right?
