  • Abstract
    In this study, the necessary and sufficient conditions for the Liu-type (LT) biased estimator are determined.A test for choosing between the LT estimator and least-squares estimator is obtained by using these necessary and sufficient conditions. Also, a simulation study is carried out to compare this estimator against the ridge estimator. Furthermore, a numerical example is given for defined test statistic.
