Best Linear Invariant Estimation for Weibull Parameters Under Progressive Censoring

Best linear invariant estimators of log reliable life are derived for a model in which failure times have a two-parameter Weibull distribution and removal of some surviving items from life test is allowed at the time of any failure. Weights for obtaining best linear invariant estimates under this model are given in tabular form for all censoring patterns for sample sizes 2 through 6.
