7.2: The Method of Moments - Statistics LibreTexts

Web2. In the method of moments one sets the sample moments equal to the population moments, and then solves for the parameters to be estimated. In this case there's only one such parameter and one uses only the first moment. Thus: θ 1 + θ = Y ¯. Consequently. θ = Y ¯ ( 1 + θ) = Y ¯ + θ Y ¯. θ − θ Y ¯ = Y ¯. WebMaximum likelihood estimation often fails when the parameter takes values in an infinite dimensional space. For example, the maximum likelihood method cannot be applied to the completely nonparametric estimation of a density function from an $\\operatorname{iid}$ sample; the maximum of the likelihood is not attained by any density. In this example, as …
