woe_adj bug

[zjplab]

代码里有这几行：

    if not adj_all_var:
        bins2 = bins.loc[~((bins['bin'] == 'missing') & (bins['count_distr'] >= count_distr_limit))].reset_index(
            drop=True)
        bins2['badprob2'] = bins2.groupby('variable').apply(lambda x: x['badprob'].shift(1)).reset_index(drop=True)
        bins2 = bins2.dropna(subset=['badprob2']).reset_index(drop=True)
        bins2 = bins2.assign(badprob_trend=lambda x: x.badprob >= x.badprob2)
        xs_adj = bins2.groupby('variable')['badprob_trend'].nunique()
        xs_adj = xs_adj[xs_adj > 1].index

但是现在badprob2并没有 所以会报错
