Abstract: Based on the order statistics of incomplete data,a regression analysis method for incomplete data is presented.The regression equation for incomplete data is established,and the best unbiased integral estimators of the regression parameters and their covariance matrix are also given.The regression analysis methods for incomplete data from extreme distribution,Weibull distribution and normal distribution are discussed in detail.As the cross information among the test data in different states is fully exploited,this present method can reach higher precision than the traditional method.
