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). WebDec 27, 2024 · The first two moments of the Beta-Binomial distribution are: Let's define and . Now, since the are independent, we know that the first two moments of the sum of the are just the sum of the first two moments of the individual : Equating sample moments to the two moments above results in one equation that solves for an estimate of the ratio …

WebJan 4, 2024 · Using the method of moments we can relate the sample mean to the expectation. X ¯ n = E [ X] = 1 + 1 1 + θ = μ. and define the estimator of θ. T n = 1 X ¯ n − 1 − 1. supposing n is big enough so that X ¯ n is not 1. I also calculated the variance of X: V a r ( X) = θ ( 1 + θ) 2 = σ 2. By the Central Limit Theorem.
