一般回归模型的最小偏差逼近
A generalization of minimum bias estimation as introduced in [6] is developed and applied to a setting in which the true model is assumed to be the ratio of real polynomials (rational function) while the approximating equation is assumed to be a polynomial of low order.
删失寿命试验数据下混合指数失效时间分布的参数估计
Statistical methods in life testing analysis have been developed in the past primarily for the case of a single failure population. In this paper a failure population which can be divided into subpopulations, each representing a different type or cause of failure, is considered. Estimates of the population parameters are obtained in the case where the subpopulations are exponentially distributed and sampling is censored at a predetermined test termination time.
