| Abstract: | In this paper,the almost unbiased ridge estimator(AURR) of regression coefficients is considered in growth curve model.We show that the mean square error(MSE) of above estimate is less than MSE of ridge estimator(RR) estimate.In the meantime,a example to test our conclusion is used. |
