Many of the mathematical models that we use are described by one or two parameters. Hence, one or two moments are sufficient for a solution. In an occasional problem, we may find that the third moment must be utilized. how can i fly in my dreams

"WebAs always, the moment generating function is defined as the expected value of e t X. In the case of a negative binomial random variable, the m.g.f. is then: M ( t) = E ( e t X) = ∑ x = r ∞ e t x ( x − 1 r − 1) ( 1 − p) x − r p r. Now, it's just a matter of massaging the summation in order to get a working formula. " - Binomial method of moments

WebBy substituting µj’s on the left-hand side of (1) by the sample moments ˆµj, we obtain a moment estimator θˆ, i.e., θˆ satisﬁes µˆj = hj(θˆ), j = 1,...,k, which is a sample analogue … WebThe method of estimation that you are describing is called method of moments. It is not maximum likelihood estimation. To do maximum likelihood you have to write down the likelihood function for your observed data based on the parametric model. Then you search for a maximum value for that function (which is often unique).

WebThe sight-resight method is able to avoid the assumption of constant detection probabilities in the binomial method-of-moment estimator (Section 9.2.3) and the parametric modeling of the detection function in the sightability model (Section 9.2.4).
