Using the maximum likelihood method, the authors studied parameter estimation and hypothesis on the equality of two Rayleigh distribution parameters under type Ⅰ censoring sample with missing data. We discussed the limiting properties of the estimator. Moreover, statistic on testing equality of the parameters from two Rayleigh distributions and its limit distribution were given.
