چکیده | ||
In this paper, a new two-parameter estimator is proposed. This estimator is a generalization of two-parameter (TP) estimator introduced by Ozakle and Kaciranlar (The restricted and unrestricted two-parameter estimator, Commun. Statist. Theor. Meth. 36 (2007) 2707--2725) and includes the ordinary least squares (OLS), the ridge and the generalized Liu estimators, as special cases. Here, the performance of this new estimator over the TP estimator is theoretically investigated in terms of quadratic bias (QB) criterion and its performance over the OLS and TP estimators is also studied in terms of mean squared error matrix (MSEM) criterion. Furthermore, the estimation of the biasing parameters is obtained, a numerical example is given and a simulation study is done as well. | ||
