What functionality should exist in a CAS that was specifically geared toward Statistics?
Symbolic algebra systems like Mathematica and Maple are often used for calculus, logic, and physics problems but are rarely used for statistics. Why is this?
What statistical constructs could be added to a symbolic algebra system to improve its use in this field? What are some specific code samples that many people would like to be able to do.
Please think about the following three users: research statistician, non-statistics researcher using statistics in another field (such as biology), statistics student.
I'll be working on SymPy's statistics code over the next few months and would like to solicit input for desired functionality. The things I use are not necessarily what the broader community uses.
