jakevdp · 2016-05-23T13:46:27Z

@JTchaoren – it looks like you're using Statsmodels. You might try asking your question on the forums for that project.

JTchaoren · 2016-05-23T13:59:17Z

OK！ Did you meet the same question?

jakevdp · 2016-05-23T14:18:07Z

No, I've not used statsmodels much at all.

amueller · 2016-10-07T22:56:09Z

LGTM thanks

jnothman · 2016-10-08T11:41:01Z
