Answer for ARMA model

Hi Max, 

 

Thanks for reaching out!

 

When this occurs, you need to specify the number of starting AR parameters you’re giving the model before fitting. Usually, 1 more than the number of lags you’re using is sufficient, but you might need to add more depending on the data. 

 

Hence, just add start_ar_lags = 4 to the fit function, like so: 

results_returns_arma_33=model_returns_arma_33.fit(start_ar_lags = 4)

 

Hope this helps!

Best,
