PSI uses five Varieties of Democracy (V-Dem) v15 indicators — Social Group Power (v2pepwrsoc), Gender Power (v2pepwrgen), Civil Liberties Equality (v2clsocgrp), Freedom from Torture (v2cltort), and Freedom from Killings (v2clkill) — aggregated via a hybrid method (geometric mean multiplied by normalized Polyarchy). The repository includes three Quarto documents: Phase 1 (measure construction and aggregation sensitivity analysis), Phase 2 (psychometric validation including internal consistency, dimensionality, and convergent/discriminant validity), and a publication-ready Appendix. Precomputed .rda results files allow reproduction of the Appendix without raw V-Dem data. All analyses conducted in R.Raw V-Dem v15 data (V-Dem-CY-Full+Others-v15.rds) is not included due to license restrictions. Download from https://v-dem.net/data/dataset-archive/ and place in data/raw/ to reproduce Phase 1 and Phase 2 from scratch. The Appendix renders from precomputed .rda files without the raw data.<a href="http://creativecommons.org/publicdomain/zero/1.0">CC0 1.0</a>00_setup.Rtype/x-r-syntaxAppendix.pdfapplication/pdfAppendix.qmdapplication/octet-streamLICENSEapplication/octet-streamPhase_1_PSI_Construction.pdfapplication/pdfPhase_1_PSI_Construction.qmdapplication/octet-streamPhase_2_PSI_Validation.pdfapplication/pdfPhase_2_PSI_Validation.qmdapplication/octet-streampsi_phase1_results.rdaapplication/octet-streampsi_phase2_results.rdaapplication/octet-streampsi-scale.Rprojapplication/octet-streamREADME.mdtext/markdown
