How to find the p,d,q values selected in auto_arima() Python?

Question

我想在训练集上运行 auto_arima()，然后使用相同的选定 p、d、q 值在测试集上评估 arima()。

Answer 1

If you're talking about this auto_arima() , it apparently

returns a fitted ARIMA model

ie an instance of this ARIMA class .

You can then directly use that class, or if you really do need the parameters, see the get_params() method .
