SUMMARY
The method of moments estimator is a statistical technique used to estimate parameters of a probability distribution by equating sample moments to theoretical moments. Specifically, the average of a sample is calculated and set equal to the expected value of the distribution, represented as u = sum E(x)/n = ehat. This method simplifies the estimation process, making it accessible for those unfamiliar with more complex statistical techniques.
