Fig. 2From: On the accuracy of short-term COVID-19 fatality forecastsComparison of predicted and reported weekly COVID-19 deaths in the US (data updated in January 2022). a Forecasts of reported weekly COVID-19 deaths in the US for 1-week forecasting horizons. Blue and red lines represent CDC ensemble forecasts [1] and regularized Euler forecasts [Eq. (6)] with \(\uplambda =10^5\), respectively. Reported COVID-19 fatalities (dashed black lines) are based on [11]. b 1-week moving averages of weekly forecasting errors of Euler–Lagrange and CDC ensemble forecasts. Solid lines indicate 1-week moving averages that are calculated based on the shown data pointsBack to article page
