1. The unit test TestLinearReg.test_solve_pinv_4 had an issue. It used 0 as a cutoff. On some machines, svd does not return a zero singular value, instead it returns a small nonzero value (due to roundoff error). Please use the revised unittests available here.
  2. Notebooks the EDA/cleaning notebook and regression notebook are now available.
  3. For those who are interested there is a intermediate git workshop happening on campus (thanks to Michael Discenza for letting us know). Here are the details:
