Our 2001 paper on Shapley value (SV) regression [1] considered estimation of the individual predictorsâ contribution to a model and the re-evaluation of the regression coefï¬cients. A recent contrasting paper [2] claims that only the ï¬rst part of the estimate of the regressorsâ importance is useful, not the re-estimation of the regression coefï¬cients. We thank the authors [2] for attracting attention of statisticians and practitioners to this problem, however, we would like to emphasize that SV regression technique with the adjusted coefï¬cients produces a meaningful model, is helpful for interpretation, and yields efï¬cient predictions. We have been considering different approaches to produce meaningful coefï¬cients for regressions with collinear predictors [3â4]. In a recent supporting work [5] (Tables 2â3 and 6), several models of ordinary least squares (OLS), stepwise OLS, adjusted SV, two-parameter ridge, and restricted regressions expressed via exponential, logit, and multinomial parameterization of the coefï¬cients of linear regression have been
