Influence Measures in Ridge Regression
Esteban Walker, Jeffrey B. Birch

Paper Summary

The article explores how ridge regression can help identify and reduce the impact of influential data points in regression analysis, especially when dealing with collinearity. The researchers found that using ridge regression can significantly change the influence of certain observations. They also developed formulas to detect these influential points in ridge regression.
