WebDec 23, 2016 · So the MoM is a practical way to estimate the parameters, leading often to the exact same result as the MLE (since the moments of the sample often coincide with the moments of the population, e.g. a sample mean is distributed around the population mean, and up to some factor/bias, it works out very well). WebMay 26, 2024 · It has to do with something called the law of the unconscious statistician. The equation in terms of its expected value is the true definition of the second central moment.
