Web23 dec. 2016 · It means that you are estimating the population parameters by selecting the parameters such that the population distribution has the moments that are equivalent to the observed moments in the sample. How is it different from MLE The maximum likelihood estimate minimizes the likelihood function. In statistics, the method of moments is a method of estimation of population parameters. The same principle is used to derive higher moments like skewness and kurtosis. It starts by expressing the population moments (i.e., the expected values of powers of the random variable under consideration) as functions of the parameters of interest. Those expressions are then set equal to the sample moments. The number of such equations is the same as the numb… ugg anna throw
