Consider a random sample of size n from a two-parameter exponential distribution, Xi ~ EXP(\theta ,\eta). Recall from Exercise12 that X1:n and \bar{X} are jointly sufficient for \theta and \eta . (Exercise12: Let X1, . . . , Xn be a random sample from a two-parameter exponential distribution, Xi ~ EXP(\theta ,\eta). Show that X1:n and \bar{X} are jointlly sufficient for \theta and \eta .) Because X1:n is complete and sufficient for \eta for each fixed value of \theta ,...
