Facets: DOS version

Windows 7, 64-bit Windows: Please run in DOSBox

Current versions of Facets are Windows-native

For complete information about Facets for Windows.

Facets 3.22 (released in 1999) is a DOS-based Rasch measurement program. It has most of the functionality of the current version of Facets, but lacks a Windows interface and has none of the enhancements since 1999. Its capacity is about 20,000 persons (elements). You may copy, distribute and use it without charge or time-limit. Of course, we hope you will want to purchase the full version of Facets (which can analyze 1,000,000 elements).

Free evaluation/student/demo version of Facets for Windows, called MINIFAC. Contains all Current Facets features except it is limited to 2,000 data points (observations). Please copy, distribute and use.



DOS-Facets, DOS precursor to the current Windows-based Facets. Final Version: 3.22, October 1999. Data capacity: 20,000+ elements.

Use Minifac instead, whenever possible!

According to Wikipedia, the human body requires about 30 minerals, maybe more. There are 60 naturally-occurring minerals in the liquid Mineral Supplement which I take daily.
