plane_cover {rplanes}R Documentation

Coverage component

Description

This function evaluates whether or not the evaluated signal interval covers the last observed value. The interval used in this plausibility component is drawn from the upper and lower bounds of the forecasted prediction interval. As such, the only accepted signal format is forecast, which will include upper and lower bounds.

Usage

plane_cover(location, input, seed)

Arguments

location

Character vector with location code; the location must appear in input and seed

input

Input signal data to be scored; object must be one of forecast

seed

Prepared seed

Value

A list with the following values:

Examples


## read in example observed data and prep observed signal
hosp <- read.csv(system.file("extdata/observed/hdgov_hosp_weekly.csv", package = "rplanes"))
hosp$date <- as.Date(hosp$date, format = "%Y-%m-%d")
prepped_observed <- to_signal(hosp, outcome = "flu.admits", type = "observed", resolution = "weeks")

## read in example forecast and prep forecast signal
fp <- system.file("extdata/forecast/2022-10-31-SigSci-TSENS.csv", package = "rplanes")
prepped_forecast <- read_forecast(fp) %>%
  to_signal(., outcome = "flu.admits", type = "forecast", horizon = 4)

## prepare seed with cut date
prepped_seed <- plane_seed(prepped_observed, cut_date = "2022-10-29")

## run plane component
plane_cover(location = "08", input = prepped_forecast, seed = prepped_seed)
plane_cover(location = "47", input = prepped_forecast, seed = prepped_seed)
