Estimating temperament curve parameter values ​​using maximum likelihood method

Abstract

The maximum likelihood method is a method for estimating the statistical parameters of the Pearson type III curve. This article focuses on the basic idea of ​​the maximum likelihood method and its procedures, steps, and value principles for estimating the statistical parameters of the Pi' type III curve. It is different in concept from methods such as the moment method, the trial-and-error line-fitting method, and the three-point method. Its basic point is that the possibility of the occurrence of the research sample is the greatest, so the maximum possibility is the original intention of the maximum likelihood method
