Then I was misinformed, and I hadn't realized it was a long-standing use.
I suspected it might be problematic for np.random.random. But
np.random.sample was only used once, and np.random.ranf not at all.
Those two didn't appear in the statsmodels code base either, I don't
think. (And random.random only appeared once in a docstring.)
So in the mean time, are there any suggestions for what this R sample
function should be called, since random.sample is apparently taken?
