Parameter Estimation and Evaluation Population and Distribution Model Population and Distribution Model A random sample XT=(X1,..,Xn)is from a popula- tion distribution fx(x). A realization x"of the random sample Xm constitutes a data set with sample size n. [Sampling Inference:The primary purpose of sta- tistical inference is to make inference of the population distribution fx(x)using an observed data x".
