摘要：
The parametric estimation is performed for two models based on the Weibull distribution: the mixture of Weibull distributions and the additive Weibull model. The estimation is carried out by a method which use the Kolmogorov-Smirnov distance as the objective. Phase-type distributions are introduced and a comparison is made between the fitted Weibull models and the phase-type fit to various sets of life data.
