Facets is innovative software breaking new ground in statistical theory. A guiding design principle has been that a useful solution now is better than a perfect solution later. Consequently, many of the statistical niceties that are taken for granted with 70-year-old statistical techniques are not yet implemented.

 

In the Hegelian conflict between theory and data, Facets regards intentional measurement-oriented, prescriptive and deliberate theory as preeminent over inevitably ambiguous data. Conventional statistics regard deterministic data as dominant over arbitrary and accidental statistical models. Since Rasch theory embodies what we demand of our data in our endeavor to construct meaning, failure of the data to generate satisfactory measures implies gross failure in the data, not in the model. This way of thinking is quite unfamiliar to those accustomed to conventional statistical methodology.

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.
