Under such circumstances, the ridge regression estimator may prove to be a viable alternative. The present paper deals with the setting up of a ridge regression model for the catalytic cracking of a chemical reactor.MarinoiuUniversitateaCristian...
β^ridge=(XTX+λI)−1XTYβ^ridge=(XTX+λI)−1XTY which comes from adding the penalty term λ||β||22λ||β||22. I have been struggling to find literature on regularizing towards a particular value. In particular, I have looked at a ridge regression model that uses the form of...
The ridge regression model has been consistently demonstrated to be an attractive shrinkage method to reduce the effects of multicollinearity. The gamma regression model is a very popular model in the application when the response variable is positively skewed. However, it is known that multicollinearit...
Ridge Regression addresses this issue by adding a regularization term to the objective function, which penalizes large coefficient values. This penalty encourages the model to distribute the impact of correlated variables more evenly, reducing their dominance. By striking a balance between model complexi...
ridge regressionsimulationzero-inflated PoissonThe zero-inflated Poisson regression model is commonly used when analyzing economic data that come in the form of non-negative integers since it accounts for excess zeros and overdispersion of the dependent variable. However, a problem often encountered when...

This study demonstrates the use of ridge regression as a method for determining those correlated variables which must be eliminated from an analysis and for maximizing the amount of information gained from a set of correlated predictors. The model is reviewed and a case study, based on an ...
The objective of the paper is to apply the statistical procedure of ridge regression to a multivariate model of criminal activity. The explanatory variables are of an economic, apprehension, and seasonal nature. The Time Shared Reactive On Line Laboratory (TROLL) computer package was used in estima...
