Methods Used to Calculate Point Estimators

Point estimators can be calculated using various methods, depending on the nature of the parameter being estimated and the characteristics of the sample data. Common methods include the method of moments, maximum likelihood estimation, and Bayesian estimation. In the method of moments, the estimator is chosen to match the sample moments (e.g., mean, variance) with the corresponding population moments.

Maximum likelihood estimation involves finding the parameter value that maximizes the likelihood function, which measures the probability of observing the sample data given different values of the parameter. Bayesian estimation incorporates prior beliefs about the parameter into the estimation process, updating these beliefs based on the observed data to obtain a posterior distribution for the parameter.
