- Abstract : the generalized shrunken prediction of finite population is introduced , using generalized shrunken least squares estimator of linear regression models . with respect to prediction mean squared error , a necessary and sufficient condition for superiority of a generalized shrunken prediction over the best linear unbiased prediction is obtained . in the case of linear combination of every unit index , a linear restricting prediction is introduced and then a necessary and sufficient condition for superiority of linear restricting prediction over the best linear unbiased prediction is devived
