| Abstract: | A likelihood approach,together with a EM-type algorithm,to jointly estimate the regression coefficient as well as the marginal distribution of the covariant in regression model with an intervalcensored data covariant is developed.Under certain conditions the procedures are convergent,and the resulting estimators are asymptotically normal. |

| Keywords: | Regression interval data EM-type algorithm asymptotically normal |
