| Abstract: | The problem of estimating the parameters in the Weibull distribution with randomly censored samples is studied. Kuhn-Tucker conditions are used to give the necessary and sufficient conditions for the problem.An algorithm of obtaining the maximum likelihood estimators under the order restrictions is proposed. |
