This video will show how to do SARIMA in R Program. Despite the stunning speed with which highly effective and safe vaccines have been developed the emergence of new variants of SARS-CoV-2 causes high rates of reinfection a major impact on health care services and a slowdown to the socio-economic system. I know there is autoarima function in r programming.

For example a single function autocorrelations computes various kinds of theoretical and sample autocorrelations. Simulation and Prediction with Seasonal ARIMA Models Functions classes and methods for time series modelling with ARIMA and related models. For example sarimasim ar9 mean5 will generate data using N 51 or 5N 01 innovations so that the constant in the model is 5 and the mean of the AR.
