SCALE=YES scales the importance measure to sum to 100%. For this reason, this extension command has not been tested with this option.Īll the measure except for FIRST and LAST sum to the overall R2. PMVD is only available in the non-US version of the relaimpo package which must be obtained fromĪnd is licensed for use only outside the United States. It can be interpreted as a weighted average over orderings among regressors, PMVD: the proportional marginal variance decomposition as proposed by Feldman.PRATT: the standardized coefficient times the correlation.BETASQ: the square of the standardized coefficient.LAST: the incremental R2 when the variable is entered last.FIRST: the R2 when only that variable is entered.LMG: also know as the Shapley value - the incremental R2 for the variable averaged over all models.MEASURE specifies one or more importance measure calculated for each ENTER variable. May help to rescale variables with very large values. Occasionally the computations fail with a singularity message. Related statistics are calculated for the ENTER variables. STATS DEPENDENT=y ENTER=x1 x2 x3 MEASURE=LMG FIRST LASTĭEPENDENT and ENTER specify the dependent variableįORCED variables are always included in the equation. STATS RELIMP /HELP prints this information and does nothing else. OPTIONS SCALE=NO^** or YES RANKS=NO^** or YES Search for the name of the extension and click Ok.Navigate to Utilities -> Extension Bundles -> Download and Install Extension Bundles.Note: For users with IBM SPSS Statistics version 21 or higher, the STATS RELIMP extension is installed as part of IBM SPSS Statistics-Essentials for R. IBM SPSS Statistics 18 or later and the corresponding IBM SPSS Statistics-Integration Plug-in for R.This package provides various relative importance measures for regression explanatory variables and shows how regression coefficients vary as the model size changes.
