Boolean Minimization in Social Science Research: A Review of Current Software for Qualitative Comparative Analysis (QCA)

Besides an increase in the number of empirical applications, the widening landscape of tailored computer programs attests to the success of qualitative comparative analysis (QCA) as a social research method. Users now have the choice between three …

Qualitative Comparative Analysis with R. A user's guide

This book is now obsolete, being replaced by this new one (also published at Springer).

Crisp-Set Qualitative Comparative Analysis (csQCA), Contradictions and Consistency Benchmarks for Model Specification

The purpose of this paper is to address and test two assumptions on which csQCA is based, namely that csQCA will generate contradictions and low consistency scores if models are ill-specified. The first part of the paper introduces csQCA in general …

A mathematical approach to the Boolean minimization problem

Any minimization problem involves a computer algorithm. Many such algorithms have been developed for the boolean minimizations, in diverse areas from computer science to social sciences (with the famous QCA algorithm). For a small number of entries …

User manual for the QCA(GUI) package in R

Although performing all available function directly from R's command line is possible, many users have expressed their desire for a user-friendly version of the QCA package with menus. Instead of designing the user interface from scratch it was a lot …

QCA – Analiza Calitativă Comparativă. Aplicații, instrumente și potențial

Științele sociale și politice sunt împărțite, în ceea ce privește cercetarea, între două lumi: cercetarea calitativă și cercetarea cantitativă. Deși în principiu este acceptat că această împărțire este artificială și că, de fapt, cele două tipuri de …
