Abstract
A stable technique for obtaining the maximum-likelihood estimate
of Weibull parameters of the life distributions of two components that
form a series system is presented. The technique requires much more
computation than the procedure of H. Kanie and Y. Nonaka (1985).
Simulation results, however, show that the standard deviation of the
estimated values of the Weibull parameters is greatly reduced. This
technique does not require the concomitant indicator and can be applied
not only for complete data but for randomly censored data
