Consider the FayHerriot model in (14.5). Suppose that Ïd , Ï2 v , and β are known.
Question:
a. Let
With a [0, 1]. Show that, under the model in (14.5), EM [Ëθd (a) θd ] = 0 for any a [0, 1].
b. Show that VM [Ëθd (a)θd ] is minimized when a = αd and that VM [Ëθd (αd )θd ] = αdÏd . Consequently, under the model, VM [Ëθd (αd ) θd ] ¤ VM[d θd ].
