MultiColl package and other packages to detect multicollinearity in R

Abstract

This work presents a guide for the use of some of the functions of the multiColl [16] package in R [19] for the detection of near-multicollinearity. The main contribution, in comparison to other existing packages in R or other econometric software, is the treatment of qualitative independent variables and the intercept in the simple/multiple linear regression model. The main goal of this paper is to show the advantages of the multiColl package in R, comparing its results with the results obtained by other existing packages in R for the treatment of multicollinearity.
