We say that a parameter h(9) is estimable if and only

We say that a parameter h(9) is estimable if and only if El a statistic T : T(X) 3 E9(T) : 15(6), V9 6 9, or equivalently, if and only if an unbiased estimator of 15(9) exists. Prove: If MB) is estimable, then h(6) is identiable. Note that the converse of the above statement is not true
