This webinar will present a set of tools developed for visualizing data quality problems in aggregate surveillance data, in particular for data which accrues over a period of time. This work is based on a data quality analysis of aggregate data used for ILI surveillance within the Distribute system formerly operated by the ISDS. We will present a method developed as a result of this analysis to ‘nowcast’ complete data from incomplete, partially accruing data, as an example of how forecasting methods can be used to mitigate data quality problems.
