Scott Sanderson 12101c55c8 STY: Don't assign variables that won't be created. 2016-09-02 12:53:01 -04:00
Scott Sanderson 8b2446aec6 ENH: Dont allow length=1 regressions/correlations.

Implemented in terms of a new preprocessor, `expect_bounded`, which
takes a tuple of `upper_bound` and `lower_bound`.
