| Abstract: | The likelihood function of four-unit hybrid system is deduced based on masked data.The maximum likelihood estimates of parameters are proposed for hybrid system composed of four units with constant failure rate and linear failure rate based on masked data.Besides,the approximate interval estimates of parameters are obtained by using likelihood ratio to construct interval estimate. |

| Keywords: | masked data four-unit hybrid system maximum likelihood estimate approximate interval estimate |
