| Research Abstract |
For the sake of establishing method of parameter estimation for distributions with threshold parameter, lifetime distributions including Weibull, gamma, lognormal and inverse Gaussian distributions, which are very important stochastic models especially in reliability and quality control, estimation methods avoiding the non-regularity problem have been proposed and then evaluated.
