Abstract
For linear regression models with interval censored
the authors have presented an ordinary iterative algorithm for the maximum likelihood estimate(MLE) on the parameters of likelihood-based equations when errors are normally distributed
and have proved the consistency between the iterative algorithm and EM algorithm
the nature of EM algorithm ensuring iterative convergence.The authors have pointed out that
the EM algorithm for the MLE on the parameters in right-censored linear regression models proposed by Murray Aitkin is merely a special case of the EM algorithm as proposed in this paper.In the end
the authors have proved the uniqueness of convergence point of EM algorithm.
