Tosmana is a tool for Qualitative Comparative Analysis (QCA).
The software can be used for csQCA (Crisp-Set Qualitative Comparative Analysis) and mvQCA (Multi-Value QCA) calculations. More informations about QCA can be found on the website of Charles Ragin
and the COMPASSS Research Group

Tosmana is provided by Lasse Cronqvist
(University of Trier, Germany).
The development of this software started in the year 2000, and after some years of discontinuity, the release of version 1.4 in June 2016 marks the resumption of work on TOSMANA. A website reset followed in June 2016 as well.
Since version 1.5., TOSMANA
does include standard fuzzy-set QCA (fsQCA) procedures as well. Further information on updates can be found here
Please note that the software is a side-line product of my work as lecturer at the University of Trier, and that I can not
offer in-depth support on the use of Tosmana or on general questions on how to perform research based on QCA.
