| Abstract: | In this paper,we modified the rank set sampling and considered a new sample method.We discussed the maximum likelihood estimation under the normal population based on MRSS.Next,we compared the result of the maximum likelihood estimation of MRSS with those of SPS,and proved the excellence of the new method. |
