Description: 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.
