bigframes.bigquery.ml.arima_coefficients#

bigframes.bigquery.ml.arima_coefficients(model: BaseEstimator | str | Series) → DataFrame[source]#

Gets the ARIMA coefficients and the weights of the external regressors for ARIMA_PLUS and ARIMA_PLUS_XREG time series models.

See the BigQuery ML ARIMA_COEFFICIENTS function syntax for additional reference.

Parameters:

model (bigframes.ml.base.BaseEstimator, str, or pd.Series) – The time series model to get the coefficients of.

Returns:

The autoregressive coefficients, the moving-average coefficients, and the constant term of the fitted ARIMA model, one row per time series. For ARIMA_PLUS_XREG models, the result has additional rows and columns holding the weight of each external regressor, or its per-category weights when the regressor is non-numeric.

Return type:

bigframes.pandas.DataFrame
