I wanna forecast a value by fitting an ARIMA model based on a time series of historical records. I’ve used the trial SuanShu 3.4.0 API. With this trial API, could I train ARMA model parameters and predict the next term value? Does the offical version of SuanShu provide some simple examples or user manual about ARIMA mode. I am new with Suanshu and any advise or help will be appreciated. Thank you.
