I can calculate means and standard deviations pretty easily in APL or J.
On the other hand, what about FFT's or PSD's? These would have applicability
beyond just statistics. Of course once linkc (sp?) is available we can all
build our own. It seems to me that APL was a pioneer in including solutions
to linear equations (domino) in the language, but that now the standard is
somewhat higher (Matlab, Mathematica, ...) and includes EISPACK, LINPACK, 
and FFT's. Of course these make the code size grow...
