+1 for these.

I'm not sure about that. I immediately thought "how about bivariate
linear regression?", but that's actually misleading in many cases.
Doing anything more general is beyond the scope of "like a typical
scientific/statistical hand calculator".
On the other hand, well-commented code showing how to do the bivariate
case would help people to implement more general cases. Ditto for
other common tasks like chi-square tests.
