A new method of regression analysis for interval censored data is presented
the regression equation for interval censored data is established
and the best unbiased integral estimators of the regression coefficients and their covariance matrix are given.The regression analysis methods for interval censored data from extreme distribution
Weibull distribution and normal distribution are discussed in detail.As the cross information among test data in different states is fully exploited
this method can reach higher precision than traditional method.
