Thank you for your suggestion, Juan. However, I have tried to specify the innovations and this doesn't seem to solve the problem. Are there really no opportunities to simulate from a (S)ARIMA model using past observations in R, besides to make the whole script from the ground? Knut Sit

[R] SARIMA simulation using time series history

2010-10-28 Thread Knut Erik Vedahl
Hi, I'm currently working with a SARIMA model from which I want to make simulations. As I understand, neither sarima.Sim nor the functions in the gsarima package use historic realizations of the time series to simulate future values. However, I want to use historic values as input and sim
