Web6.1 Method of moments estimator The method of moments is a very simple but useful approach to nding an estimator. The idea is as follows. For a parametric model p(x; ), its moments are determined by the underlying parameter . For instance, the rst moment is m 1( ) = E[X] = Z xp(x; )dx and the second moment is m 2( ) = E[X2] = Z x2p(x; )dx WebOther Methods Based on the MoM.
