Abstract: On the basis of the maximum likelihood method, the present paper deals with the parameter estimation and hypothesis testing on the equa lity of two exponential distribution under Type Ⅰ censoring sample with missed data. The consistency and asymptotic normality of the estimations have been proved. Moreover, statistic on testing equality of two exponential distributions and its limit distribution are given.

Key words: Type Ⅰ censored sample, missing data, maximum likelihood estimation
