Dear all
I have data on the number of daily infections by COVID-19 and I would like to make predictions for the coming days using ARIMA (2, 1, 3) . The series contains 100 observations (23rd March to 30 June) and I have tried using Predict covid_19 Moz, y dynamic (d (30 Jun)) but I can only get the forecast within (100 days) and not out of sample.
can someone help on this
