%0 Journal Article %T Comparison of the r-(k,d) class estimators to some estimators by the mean square error matrix criteria %A Nilg¨¹n Y£¿ld£¿z %J - %D 2018 %X The ordinary leastsquares, the principal components regression and the Liu-type estimators are special cases of ther-(k,d)class estimators, for regression models with multicollinearity. In thisa rticle we derived conditions for the superiority of ther-(k,d) classestimatoroverotherestimatorssuch as ordinaryleastsquares, principalcomponentandLiu-typeestimatorbased on the mean square error matrix(MSEM)criterion. Finally, a numericale xample and a Monte Carlo simulation are also given to show the theoretical results %K Liu-tipi tahmin edici %K r-(k %K d )S£¿n£¿f Tahmin Edici %K Temel bile£¿enler regresyonu %K Matris Hata Kareler Ortalamas£¿ %K £¿oklu £¿£¿ £¿li£¿ki %U http://dergipark.org.tr/jssa/issue/37877/437683
