Makes a tidy summary dataframe of the results of the function nowcast()
Arguments
- object
A nowcaster object generated by
nowcast()- quantiles
A vector specifying the quantiles to include in the summary
- ...
Additional options to pass to summary.
Value
A summary tibble of the nowcast results, it specifies: true date, strata, mean, standard deviation, median, and quantiles
Examples
# Load the data
data(denguedat)
# Run a nowcast with very few iterations
# change to method = "sampling" when working and remove the iter = 10
now <- as.Date("1990-10-01")
# perform nowcasting
ncast <- nowcast(denguedat, "onset_week", "report_week",
now = now, method = "optimization",
seed = 2495624, iter = 10
)
