.. ipython:: python

import statsmodels.api as sm
from statsmodels.formula.api import ols

moore = sm.datasets.get_rdataset("Moore", "carData",
                                 cache=True) # load data
data = moore.data
data = data.rename(columns={"partner.status":
                            "partner_status"}) # make name pythonic
moore_lm = ols('conformity ~ C(fcategory, Sum)*C(partner_status, Sum)',
                data=data).fit()

table = sm.stats.anova_lm(moore_lm, typ=2) # Type 2 ANOVA DataFrame
print(table)
