Parameter Estimation and Evaluation Population and Distribution Model Population and Distribution Model Remarks: Usually,the true parameter value 0o is unknown,and one is interested in making inference of 0o using an observed data x". Traditionally,problems of statistical inference are di- vided into problems of estimation and hypothesis test- ing.In this chapter,we are interested in estimating 00. We shall introduce two most commonly used estima- tion methods,namely the maximum likelihood estima- tion (MLE)and the generalized method of moments estimation (GMM).
