Maximum Likelihood Estimates of the Parameters in Heteroscedastic Regression Model with Linear Constraint |
| |
Abstract: | This paper,using method of maximum likehhood estimates,gives maximum likelihood estimates β and A in Heteroscedastic Regression Model with linear constraint Hβ =C.Then,the properties of estimated parameters and the remnant of the model were discussed.The conclusions gained have some theoretical and practical significance for more research and application. |
