Can we identify ARIMA($p,d,q$) model without looking at the ACF and PACF plots?
I am trying to write a generalized R programme for fitting time series models.

We may find out the orders $p$, $d$ and $q$ from the ACF and PACF plots, but I want to know how to identify them from the numerical values of the ACF and PACF.

Thanks in advance, your help will be highly appreciated.

Can we identify ARIMA(p,d,q) model without looking at ACF and PACF plot. I am trying to write generalized R programme for fitting time series model.

By manually we finding out order for p,d,q from ACF and PACF plot but i want to know how to identify it from acf and pacf value which getting from when we plot acf and pacf.

Thanks in advance  ,
