This project corresponds to the following paper:
Neubauer, A. B., Voelkle, M. C., Voss, A., & Mertens, U. K. (2020). Estimating reliability of within-person couplings in a multilevel framework. *Journal of Personality Assessment, 102*, 10-21. doi: 10.1080/00223891.2018.1521418.
The following material can be found in this project:
- The folder "01_Simulation scripts" contains the R code used to create the simulated data:
- simulation script step 1 create and save data.R: code to create 291,600 simulated data sets.
- simulation script step 2 analyze data and store results.R: code to analyze the 291,600 simulated data sets; creates 291,600 result files.
- simulation script step 3 combine results.R: combines the 291,600 result files in one data file (results combined. RData).
- The folder "02_Analyze simulated data" contains the R code used to analyze the results of the simulation study:
- results combined. RData: Data file created with the R code "simulation script step 3 combine results.R"; used as input for the anlysis scripts in this folder.
- 01_analyze simulated data simulation results.R: Requires the data file "results combined. RData". Code to reproduce the main results of the simulation study reported in the manuscript.
- 02_analyze simulated data additional results.R: Requires the data file "results combined. RData". Code to reproduce the additional results of the simulation study reported in Appendix B: Additional Analyses.
- The folder "03_Data and Analysis scripts" contains the data used in the empirical example of the study (+ the data dictionary), as well as the R code to reproduce the results of the empirical example reported in the manuscript.
- Appendices A - C accompanying the article.
- wpcr.R: code for the WPCR function estimating within-person coupling reliability for each individual from the raw data.
- wpcr.xslx: Excel sheet that can be used (a) to estimate WPCR from published data and (b) to determine the number of repeated measurements necessary to obtain a requested level of WPCR.
