<p>Predictive accuracy of the time-series models. The number of PRRSV-positive submissions was partitioned into training and test datasets. The training dataset included the first 416 weeks (January 2011–December 2018), and the test dataset comprised 12 weeks starting January 7 to March 25, 2019. A rolling 12-step-ahead forecast was applied to assess the predictive performance of ARIMA, ETS, RF, and RNN models.</p>
