Estimasi Parameter Data Tersensor Tipe I Berdistribusi LoglogistikudMenggunakan Maximum Likelihood Estimate dan IterasiudNewton-Rhapson

摘要

Survival analysis is one of the topics in the field of mathematics which deals with statisticaludanalysis of the time until the occurrence of one or more a particular event. The purposes of thisudstudy are to obtain the survival model and to estimate the parameters of the type I censored dataudwhich log-logistic distributed. Maximum likelihood estimate was used to estimate the unknown parameters.udBased on the results and discussion, if the exact values of the parameters γ and β are analyticallyuddifficult to obtain, then the numerical approach by the Newton-Rhapson iteration can be used toudapproach the values of both parameters.
