Method of moments radar
WebA general answer is that an estimator based on a method of moments is not invariant by a bijective change of parameterisation, while a maximum likelihood estimator is invariant. Therefore, they almost never coincide. (Almost never across all possible transforms.) Furthermore, as stated in the question, there are many MoM estimators. WebFind an estimator of ϑ using the Method of Moments. 2.3.2 Method of Maximum Likelihood This method was introduced by R.A.Fisher and it is the most common method of constructing estimators. We will illustrate the method by the following simple example. Example 2.19. Assume that Yi ∼ iid Bernoulli(p), i = 1,2,3,4, with probability of
