OneWayLS.fitjoint()

fit a joint fixed effects model to all observations

The regression results are attached as lsjoint.

The contrasts for overall and pairwise tests for equality of coefficients are attached as a dictionary contrasts. This also includes the contrasts for the test that the coefficients of a level are zero.

>>> res.contrasts.keys()

[(0, 1), 1, ‘all’, 3, (1, 2), 2, (1, 3), (2, 3), (0, 3), (0, 2)]

The keys are based on the original names or labels of the groups.

TODO: keys can be numpy scalars and then the keys cannot be sorted
