are the d.o.f. always obvious for these stats? or are these
actually matrices that also give you the d.o.f and p-value?

$Fstat and $chisq return scalars, but IMO the df should be clear
enough to people who are likely to make use of these things: one
has the $ncoeff accessor and one knows how to subtract 1 ;-)
