Let b be an estimator for Î² in the model for GVFs in (9.13). Let B=ty / tx and á¸ =á¹«y / á¹«x. Suppose that á¸ and á¹«x are independent. a. Using the model in (9.13) and the result in
Suppose that á¸ and á¹«x are independent.
a. Using the model in (9.13) and the result in (9.2), show that we can estimate V (á¸) by
b. Now let B be a proportion for a subpopulation, where tx is the size of the subpopulation and ty is the number of units in that subpopulation having a certain characteristic. Show that á¹¼ (á¸) = b á¸ (1 á¸)/Ëtx and that á¹¼ (á¸) = á¹¼ (1 á¸).
