This paper discusses maximum likelihood parameter estimation in the Pareto distribution for multicensored samples. In particu- lar, the modality of the associated conditional log-likelihood function is investigated in order to resolve questions concerninc the existence and uniqurneas of the lnarimum likelihood estimates.For the cases with one parameter known, the maximum likelihood estimates of the remaining unknown parameters are shown to exist and to be unique. When both parameters are unknown, the maximum likelihood estimates may or may not exist and be unique. That is, their existence and uniqueness would seem to depend solely upon the information inherent in the sample data. In viav of the possible nonexistence and/or non-uniqueness of the maximum likelihood estimates when both parameters are unknown, alternatives to standard iterative numerical methods are explored. |
