Plot Nowcast Evaluation by Delay — plot_nowcast_eval_by

Plots evaluation metric as a function of delay, faceted by group. The y-axis shows how much the nowcast improves over raw observed values, across all delays. Background shading indicates the direction of improvement.

Usage

plot_nowcast_eval_by_delay(
  x,
  indicator = "SMAPE_improvement_med",
  color_good = "dodgerblue1",
  color_bad = "firebrick1",
  ...
)

Arguments

x: A nowcast_eval_results S7 object from nowcast_eval().
indicator: Character. Which metric to plot on the y-axis. One of: "SMAPE_improvement_med" (default), "SMAPE_improvement_mean", or "proportion_pred_is_better".
color_good: Character. Fill colour for the "better" region.`.
color_bad: Character. Fill colour for the "worse" region.`.
...: Ignored.

Value

A ggplot object.

Examples

input <- generate_test_data()
eval_res <- nowcast_eval(
  df = input,
  col_date_occurrence = date_occurrence,
  col_date_reporting = date_report,
  col_value = value,
  n_past = 10,
  time_units = "days"
)
#> Warning: n_past (10) exceeds available reporting periods (8). Will be using the max available instead: 7
