Hi Janet,
I'm not arguing against the substance of what you wrote.
<nit picking>
- statistical data modelling
Not a good example. I don't understand how Excel works, but I know its stats functions are crap because there is an external standard to test them against. Equally I know the functions in SAS are brilliant. Both are closed source.
There is a question about the rights inherent in a data model, especially those used in public policy, but again that is an important fight for others.
Janet
