Parameter Estimation and Evaluation Population and Distribution Model Population and Distribution Model Because one can obtain the conditional PDF of Yi given Xi as follows: f(t)=λ(t)S(t), where the survival function S(t)=eJλx(s)ds we can estimate 0o by the so-called maximum likelihood es- timation (MLE)method.
