Request for measures of predictor importance in regression

Technote (troubleshooting)


I am conducting regression analysis in which there are high correlations among the predictors. I would like to employ the following measures of relative predictor importance: Kruskal's Relative Importance Algorithm; Shapley Value Regression; Penalty and Reward Analysis. Are these techniques available in SPSS?

Resolving the problem

The importance measures that you listed - Kruskal's relative importance, Shapley Value Regression, and Penalty & Reward - are not available in SPSS. A request has been filed with SPSS Development that they be added to a future release of SPSS.

There is an extension command, STATS_RELIMP, available from developerWorks ( that provides a dialog box interface to the R relaimpo package, which includes several measures of relative importance, including Shapley values, but not Kruskal's measure or Penalty & Reward analysis.
