Summarise a dataframe containing draws of reporting squares

This function ingests a long tidy dataframe containing many draws of reporting squares across each reference time, by summing over all the counts reported at each delay d.

Usage

aggregate_df_by_ref_time(nowcast_draws_df)

Arguments

nowcast_draws_df

Dataframe containing draws of a reporting square. Must contain the following columns: time, delay, draw, count.

Value

summary_df Dataframe containing the nowcasted expected observed total observations at each reference time.

Examples

nowcast_draws_df <- data.frame(
  time = c(1, 1, 1, 1, 2, 2, 2, 2),
  delay = c(1, 2, 1, 2, 1, 2, 1, 2),
  draw = c(1, 1, 2, 2, 1, 1, 2, 2),
  count = c(3, 6, 4, 7, 1, 2, 2, 3)
)
summary_df <- aggregate_df_by_ref_time(nowcast_draws_df)
print(summary_df)
