Then we get MSE(β^GRD(k),β)=0.323 and MSE(β^GRD,β)=0.597, that is to say the new estimator is better than restricted difference-based estimator.Now we see theorem 21β^′W+2kI-1β^=0.0578<σ237That is to say our numerical example satisfied with theorem The conditional ridge-type estimation in singular linear model with linear equality restriction.

This also means our method is meaningful in practice.ConclusionsIn this article, we present a new generalized difference-based ridge estimator that can be applied in the presence of multicollinearity in a partial Some conclusion remarks are given in section “Conclusions”.The model and differencing-based estimatorIn this section we use a difference-based method to estimate the linear regression coefficient vector β.

doi: 10.1080/00401706.1997.10485117. [Cross Ref]Roozbeh M, Arashi M, Niroumand HA. For this, we investigate the difference Δ=MSEM(β^GRD,β)-MSEM(β^GRD(k),β), when Δ is nonnegative definite matrix, β^GRD(k) is preferred to β^GRD. It is shown that for small values of the ridge parameter k, the new estimator is MSEM-superior to the generalized restricted difference-based estimator over an interval depending on the design points In this paper, we simulate the response from the following model:y = x1iβ1 + x2iβ2 + x3iβ3 + x4iβ4 + f(ti) + ϵi31where i = 1, …, n, ϵ ∼ (0, σ2V) which the elements of V is vij = (0.1)|i-j| and σ = 0.1,

The scalar valued mean square error MSE is given by MSE(b∗, β) = E[(b∗-β)′(b∗ - β)] =  tr [ MSEM(b∗, β)].Using Eq. (20), we obtainE(β^GRD(k))=-k(kW+I)-1Wβ23andVar(β^GRD(k))=σ2(kW+I)-1W(kW+I)-124Thus,Var(β^GRD)=σ2W25Then, the difference Var(β^GRD)-Var(β^GRD(k)) can be expressed asVar(β^GRD)-Var(β^GRD(k))=σ2(kW+I)-1(k2W3+2kW2)(kW+I)-126Since W is an nonnegative doi: 10.1002/(SICI)1099-1255(200003/04)15:2<187::AID-JAE548>3.0.CO;2-B.
