Before Change

    wexog = wexog / weights
    
    dep = wdep
    exog = pd.DataFrame(wexog, columns=mod.exog.vars)
    
    ols = IV2SLS(dep, exog, None, None, weights=weights)
    ols_res = ols.fit("unadjusted")

After Change

    weights = weights.reindex(mod.dependent.entities)
    
    dep = mod.dependent.dataframe * mod.weights.dataframe.values
    dep = dep.groupby(level=0).sum()
    dep = dep.reindex(mod.dependent.entities)
    dep = dep / weights.values

    exog = mod.weights.dataframe.values * mod.exog.dataframe
    exog = exog.groupby(level=0).sum()
