R also has a package called forecast, which contains many forecasting functions for time series and linear models. It also contains a very useful function calledauto.arima, which returns the best ARIMA model according to either AIC, AICc or BIC value. The function conducts a search over possibl...
n_fits: int, optional (default=10) If random is True and a "random search" is going to be performed,n_iter is the number of ARIMA models to be fit. return_valid_fits: bool, optional (default=False) If True, will return all valid ARIMA fits in a list. If False (by default), w...
When I use the same dataset and use auto_arima function (like pm.auto_arima(ts_data)), it's taking a bit more time (measured with timeit): 1.07 s ± 53.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each) R implementation of auto.arima is roughly 10 times faster. What...

I used the function arima() in R to fit some autoregressive moving average models with orders up to thirteen, both with and without the astronomical regressor. The best model, using the Aktaike information criteria (see the Wikipedia page Aktaike information criterion), was $$Y{_t}=\beta_...
