QCApro-package: Professional Functionality for Performing and Evaluating Qualitative Comparative Analysis

Description

QCApro is a successor package to the QCA package, with QCA 1.1-4 as its basis (Dusa and Thiem 2014; Thiem and Dusa 2012; 2013a; 2013b; 2013c). Just like its predecessor, QCApro implements the method of Qualitative Comparative Analysis (QCA)---a family of techniques for analyzing configurational data in accordance with the INUS theory of causation (Mackie 1965; 1974), but it has fixed various technical and methodological problems of the QCA package, it includes many new features and enhancements for applying QCA, and it provides several purpose-built functions for testing properties of QCA and QCA-related procedures.

Three variants can currently be processed by QCApro: crisp-set QCA (csQCA; Ragin 1987), multi-value QCA (mvQCA; Cronqvist and Berg-Schlosser 2009; Thiem 2013; 2014) and fuzzy-set QCA (fsQCA; Ragin 2000; 2008). A subvariant of csQCA called temporal QCA (tQCA) is also available (Caren and Panofsky 2005; Ragin and Strand 2008).

Several datasets from various areas are integrated in QCApro so as to facilitate familiarization with the package's functionality. Currently covered are business, management and organization (d.stakeholder), education (d.education), environmental sciences (d.biodiversity), evaluation (d.transport), legal studies (d.napoleon), political science (d.jobsecurity, d.partybans, d.represent), public health (d.health, d.tumorscreen), urban affairs (d.urban), and sociology (d.homeless, d.socialsecurity). For more details, see the datasets' documentation files. Also note that many more datasets for QCA are available on the COMPASSS bibliography website.

As an additional resource, QCApro includes a comprehensive glossary for Configurational Comparative Methods. The glossary is directly accessible via the link 'User guides, package vignettes and other documentation' in the package's help index or the 'doc' folder of the package's installation folder.

If you make use of the QCApro package in your work, please acknowledge it in the interest of good scientific practice and transparency. The package citation displays on loading the package or by using the command citation(package = "QCApro") after loading. The aforesaid command also provides a suitable BibTeX entry. To browse the latest news about the QCApro package (bug fixes, enhancements, etc.), enter news(package = "QCApro") (for version 1.0-0, this details all changes in relation to QCA 1.1-4).

Happy QCAing!
