abstract: Nowcasting right-truncated epidemiological data is critical for timely public
  health decision-making, as reporting delays can create misleading impressions of
  declining trends in recent data. This package provides nowcasting methods based
  on using empirical delay distributions and uncertainty from past performance. It
  is also designed to be used as a baseline method for developers of new nowcasting
  methods. For more details on the performance of the method(s) in this package applied
  to case studies of COVID-19 and norovirus, see our recent paper at <https://wellcomeopenresearch.org/articles/10-614>.
  The package supports standard data frame inputs with reference date, report date,
  and count columns, as well as the direct use of reporting triangles, and is compatible
  with 'epinowcast' objects. Alongside an opinionated default workflow, it has a low-level
  pipe-friendly modular interface, allowing context-specific workflows. It can accommodate
  a wide spectrum of reporting schedules, including mixed patterns of reference and
  reporting (daily-weekly, weekly-daily). It also supports sharing delay distributions
  and uncertainty estimates between strata, as well as custom uncertainty models and
  delay estimation methods.
