What is the expected output? What do you see instead?
No error

What version of the product are you using? On what operating system?
Winpython 2.7.5.2 (64 bit) using statsmodels 0.5

Please provide any additional information below.
This example works in winpython 2.7.5.1 using statsmodels 0.4.3
This should work according the examples listed here: http://statsmodels.sourceforge.net/devel/

My mistake, I forgot to add the required dependency "patsy" to the package list. I'll fix this in the next release.

In the meantime, you may install patsy using the WinPython Control Panel:

1. Download the 2.7/64bit version of patsy here:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#patsy

2. Execute the WinPython Control Panel

3. Drag an drop the installer downloaded at step 1 and click on "Install"

Status: Done
