I'm using the Package manager to try and install statsmodels in Canopy on my MacBook with Mavericks.
I got this error: Action: install statsmodels-0.5.0-2.egg The package manager has encountered error HTTP Error 404: NOT FOUND: https://api.enthought.com/eggs/osx-64/patsy-0.2.0-1.egg
So I tried installing patsy also via the package manager and got the same message: Action: install patsy-0.2.0-1.egg The package manager has encountered error HTTP Error 404: NOT FOUND: https://api.enthought.com/eggs/osx-64/patsy-0.2.0-1.egg
Try installing patsy and statsmodels using pip.
