timeseries forecasting, finding RSS of ARMA model












0















After I fit the ARMA (2,1) and ARMA (3,2) model, I need to find the RSS(Residual sum of squares) and comparing them .
Right now my code fetches only the AR and MA coefficients/parameters.
below is the snap shot of my code.[enter image description here][1]



Code:



from statsmodels.tsa.arima_model import ARMA
result = sm.tsa.ARMA(model, (2,1)).fit()
print (result.params)


And also how do we add a confidence interval for the estimated parameters ? Is there any other function ?
