Short Introduction to the Generalized Method In general, sample statistics each have a counterpart in the population, for example, the correspondence between the sample mean and the population expected value. The natural next step in the analysis is to use this analogy to justify using the sample moments as bases of estimators of the popula-tion parameters. This was the original …
