MEMORE_vs_wsMed

introduction

The MEMORE reports below are stored reference output, not rerun by this vignette. Compare estimates only after matching difference direction, model structure, missing-data handling and interval settings. Standardized results require matching the SD definition as well: wsMed uses marginal model-implied difference-component SDs. Matching raw estimates does not imply matching standardized estimates or confidence intervals.

For moderation, see Standardized moderated mediation. This vignette does not establish agreement between the programs for moderated standardized effects.

This document presents a comparison between the MEMORE 3.0 (SPSS Plugin) and wsMed (R Package) outputs.

parallel mediation

We analyze a three-mediator parallel mediation model, comparing the results obtained from both methods.
