1. Introduction, what is meant by impact? When considering the impact that is generated as a result of research, a number of authors and government recommendations have advised that a clear definition of impact is required (Duryea, Hochman, and Parfitt 2007; Grant et al. 2009; Russell Group 2009).From the outset, we note that the understanding of the term impact differs between users and ...

The forecast plot shows that the model indeed does a better job than the SRW model of tracking cyclical changes (i.e., unusually good or bad years): However, the MSE for this model is still significantly larger than what we obtained for the ARIMA(0,1,1)x(0,1,1) model. If we look at the plots of residuals, we see room for improvement.
