Flip columns of X in poisson2binom (branch:poisson2binom) #38

Open pcarbo opened 1 year ago

From @stephens999: Presumably to make the Poisson approximation to binomial as good as possible, you want to flip each column of X so that 1 is the less frequent of the two outcomes before fitting the Poisson model?
