معالجة مشكلة الازدواج الخطي باستخدام انحدار الحرف : دراسة تطبيقية على دالة الإنفاق الاستهلاكي في الجزائر خلال الفترة 1970-2011

الملخص EN

This paper attempts to solve the multicollinearity problem which appears in the multiple linear regression models by deploying Ridge’s regression and without omitting any of the explanatory variables which may cause this problem.

We have applied the Ridge’s regression to solve the multicolineraty problem in the consumption function in the case of Algeria, using real data from different sources that cover the period from 1970 to 2011.
