This seems like a reasonable idea to me -- but be warned that there
are actually quite a few slightly-different definitions of "quantile"
in use. R supports 9 different methods of calculating quantiles
(exposed via an interesting API: their quantile function takes a type=
argument, which is an integer between 1 and 9; the default is 7). And
there's currently an open issue at numpy discussing whether numpy
implements the right approaches:
https://github.com/numpy/numpy/issues/10736
So this would require some research to decide on which definition(s)
you wanted to support.
