Python中Arima预测问题
我在Python调用statsmodels中的ARIMA().fit()时系统会出现如下告警信息。有谁知道为什么会有这些信息?这些信息是否代表建立的模型有问题?以下如何去除这些告警?谢谢了!
ValueWarning: An unsupported index was provided and will be ignored when e.g. forecasting.
' ignored when e.g. forecasting.', ValueWarning)
HessianInversionWarning: Inverting hessian failed, no bse or cov_params available
'available', HessianInversionWarning)
FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.
