Question:
Let {Yi} be independent Poisson random variables. Show by the delta method that the estimated asymptotic variance of ∑ai log(Yi) is ∑a2i/yi. [This formula applies to ML estimators of parameters for the saturated loglinear model, which are contrasts of {log(yi)}. Formula (14.9) yields the asymptotic covariance structure of such estimators.]
