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 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. grinch plastic canvas

WebThe method of moments is a way to estimate population parameters, like the population mean or the population standard deviation. The basic idea is that you take known facts about the population, and extend those ideas to a sample. For example, it’s a fact that within a population: Expected value E (x) = μ For a sample, the estimator
