    from statsmodels.formula.api import ols

                                     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)
