Pandas 0.8.1:git
import pandas as pd a=pd.Series([0, 1, 3, 6]) a.mean(), a.std(), a.var() a.values.mean(), a.values.std(), a.values.var()
I would expect both last lines to return the same result. However, the former returned:github
(2.5, 2.6457513110645907, 7.0)
and the latter:code
(2.5, 2.2912878474779199, 5.25)
