3.3 Other Estimators

Оглавление

For many estimators, a delta method argument can yield a limiting normal distribution. For example, a CLT for and a delta method argument yields an elementwise asymptotic distribution of . Let denote the th element of . If and denote the components of and , respectively, then the th diagonal of is


We obtain the asymptotic distribution of . A similar argument can be made for the off‐diagonals of . Under the conditions of Theorem 1,


where is


Under IID sampling, the infinite sum above reduces to


Applying the delta method for function , we obtain
