Implements Condition Threshold Sweep-Single (CTS-S), Condition Threshold Sweep-Multiple (CTS-M), Outcome Threshold Sweep (OTS), and Dual Threshold Sweep (DTS) for systematic exploration of threshold calibration effects on crisp-set QCA results. These methods extend traditional robustness approaches by treating threshold variation as an exploratory tool for discovering causal structures. Also provides Fiss (2011) <doi:10.5465/amj.2011.60263120> core/peripheral condition classification via compute_fiss_core() and generate_fiss_chart(), enabling four-symbol configuration charts that distinguish core conditions (present in both parsimonious and intermediate solutions) from peripheral conditions (intermediate only). Built on top of the 'QCA' package by Dusa (2019) <doi:10.1007/978-3-319-75668-4>, with function arguments following 'QCA' conventions. Based on set-theoretic methods by Ragin (2008) <doi:10.7208/chicago/9780226702797.001.0001> and established robustness protocols by Oana and Schneider (2024) <doi:10.1177/00491241211036158>. This package supersedes 'TSQCA'; see the NEWS file for migration guidance.https://github.com/r-universe/im-research-yt/actions/runs/30001015830Thu, 23 Jul 2026 05:58:35 GMTThSQCA2.0.5successhttps://im-research-yt.r-universe.devhttps://github.com/im-research-yt/thsqcaThSQCA_Reproducible_EN.RmdThSQCA_Reproducible_EN.htmlThSQCA Reproducible Code (English)2026-05-14 04:47:042026-05-14 04:47:04ThSQCA_Tutorial_EN.RmdThSQCA_Tutorial_EN.htmlThSQCA Tutorial (English)2026-05-14 04:47:042026-05-14 04:47:04
