This paper mainly discusses parameters＇ maximum hkelihood estimation of the two 0-1 populations which are partially missing data. At the same time, it proved the strong consistency and asymptotie normality of the esitimation, and present limit distribution of likelihood ratio test statistic under the field of large sample.%文章主要讨论了两个0-1总体均具有部分缺失数据时的参数的极大似然估计,并证明了估计的强相合性和渐进正态性,给出了大样本场合下的似然比检验统计量的极限分布。
