Abstract

A regression analysis of the failure time is considered when the failure time is a random censored and has the log-logistic distribution. The regression model has been used to identify the relationship between the failure time and the explanatory variables. The Maximum Likelihood estimates and confidence intervals for the parameters of the model are derived and applied for liver cancer's patients.
