广义岭回归:多元线性回归模型的有偏估计

Generalized Ridge Regression: Biased Estimation for Multiple Linear Regression Models

Román Salmerón Gómez, Catalina García García, Guillermo Hortal Reina

AI总结:

本文针对多元线性回归中回归变量非正交导致普通最小二乘估计不佳的问题,系统研究了广义岭回归的估计、均方误差、拟合优度及自助法推断。

摘要:

当计量经济学线性模型的回归变量非正交时,众所周知,使用普通最小二乘法进行估计可能会出现各种问题,从而阻碍该模型的使用。岭回归是最常用的替代方法;然而,其广义版本却很少被分析。本文研究了这一广义版本的估计问题,以及其均方误差的计算、拟合优度和自助法推断。

英文摘要:

When the regressors of a econometric linear model are nonorthogonal, it is well known that their estimation by ordinary least squares can present various problems that discourage the use of this model. The ridge regression is the most commonly used alternative; however, its generalized version has hardly been analyzed. The present work addresses the estimation of this generalized version, as well as the calculation of its mean squared error, goodness of fit and bootstrap inference.
