Real-time forecasting of data revisions in epidemic surveillance streams
Fig 5
Evaluation of forecasts for fractions, aggregated by lag.
(A) Forecasts of the fraction of COVID-19 insurance claims based on CHNG outpatient insurance claims data. (B) Forecasts of the fraction of positive COVID-19 antigen tests based on Quidel antigen tests data. Solid lines represent the mean WIS, , which approximates absolute relative errors between the most recent report and the target, averaged over locations and reference dates for each lag. Shaded areas indicate the 10th to 90th percentile interval.
