In multiple regression analysis, the independent variables should be uncorrelated within each other. If they are highly intercorrelated, this serious problem is called multicollinearity. There are several methods to get rid of this problem and one of the most famous one is the ridge regression. In this paper, we will propose some modified ridge parameters. We will compare our estimators with so...

In this paper we discuss Milstein type methods with implicitness for solving Itô stochastic differential equations (SDEs). For different Milstein type methods, the regions of mean-square (MS) stability are examined. The drift implicit balanced Milstein (DIBM) method and the semi-implicit balanced Milstein (SIBM) method are proposed in this paper. The obtained results show that the MS-stability ...
