| Abstract: | The paper discussed the two-stage estimate of regression parameters in the growth curve model. An based resuh of on what conditions the two stage estimate of the estimable function is unbiased are given, furthermore, it has been tested that two common two-stage estimates are unbiased estimates. |
| Keywords: | regression parameters error covariance matrices the two stage estimate unbiased estimate |
