I would also be very excited about a solid statistics proposal. The 
ticket Aleksey links to is a good start (as is the experience report 
linked from there), although I think that it would be possible to 
implement a core library with less type-trickery than he supposes. Such 
an interface wouldn't necessarily be perfectly statically safe, but 
other, tricker interfaces could be built on top of it (just as we have 
fancier type-level interfaces with statically checked dimensions on top 
of lower-level matrix libs, etc.). I envision a set of tools that let 
users get up and running with loading a dump of data and calculating a 
set of metrics on it with only a few lines. It should be designed such 
that the basic framework is easily extensible with various other 
analyses, and such that analyses compose fairly straightforwardly. Which 
indeed amounts to some Frame-type structure, and a core set of functions 
on it :-)
