This blog collects notes on threshold-sweep QCA, the ThSQCA R package, and data analysis for marketing research.

Three browser tools are already available for generating R code: the QCA Quickstart for a first truthTable() and minimize() script, the Sweep Builder for turning a fixed-threshold QCA setup into ThSQCA sweep code, and the Scale Maker for building a scale from survey items step by step, together with the matching R script.

The articles are arranged in reading order on the home page. If you are new, start from the top. Technical posts with reproducible R code are in the beginner’s series for ThSQCA.
