Regression analysis method for type-Ⅰcensored data

Regression analysis method for type-Ⅰ censored data was presented.The regression equation for type-Ⅰ censored data was established.The best unbiased integral estimators of the regression coefficients and the standard deviation,the point estimators and confidence intervals of percentiles were given.The regression analysis methods for type-Ⅰ censored data from extreme distribution,Weibull distribution,normal distribution and location-scale distribution were discussed in detail.As the experimental information at the censoring time and the cross information among test data in different states were fully exploited,the presented method could reach a high precision.The method provides a feasible and effective approach to life prediction and reliability estimation of products when the test time or expense are limited.
