Managing Data Revisions
Note
This page is under development.
Data requirements
Methods
- Excluding data from known backlog or major revision periods
- Flagging and annotating revision events so downstream analyses can account for them
- Redistributing negative entries in reporting triangles across neighbouring cells
- Nowcasting methods that model cumulative counts without enforcing a proper CDF (i.e. monotonically increasing) can accommodate negative increments directly
- Methods that allow an improper PMF, such as
baselinenowcast, can also handle negative counts in the reporting triangle - Many methods can be used without modification when negative counts are present for individual cells provided the net count for each delay is non-negative
