ARMAResult._specification

ARMAResult._specification()

Compact specification label, widening only as the model does.

Example

>>> rng = np.random.default_rng(0)
>>> y = rng.standard_normal(200)
>>> ARMA(y, order=(1, 1)).fit()._specification()
'ARIMA(1, 0, 1)'
>>> SARIMA(y, order=(1, 0, 0), seasonal_order=(1, 0, 0, 4)).fit()._specification()
'SARIMA(1, 0, 0)(1, 0, 0, 4)'
>>> X = rng.standard_normal((200, 1))
>>> ARIMAX(y, order=(1, 0, 0), exog=X).fit()._specification()
'ARIMA(1, 0, 0)+X1'

Return type:
