In ericmkeen/shipstrike: Utilities for spatially- and temporally-explicit predictions of whale-ship collisions

Outcome validation simulation

Description

This function replicates the validation exercise from Keen et al. (2023) to determine what our strike detection rate would need to be in order for our results to be plausible given that we have never observed a strike in our study area.

Usage

outcome_validation(
  outcomes,
  eventcol = "mortality2.2",
  observations = 0,
  scaling_factor = 1,
  years = 10,
  months = 6:9,
  iterations = 1000,
  toplot = FALSE
)

Arguments

outcomes	A data.frame of results from the shipstrike::gather_outcomes() function.
observations	The number of observed strike events during observation period.
scaling_factor	Deprecated – keep at 1.
years	Years of observation.
months	Months of effort during each year.
iterations	Number of iterations to use for randomization routine.
toplot	Produce plots?

Value

A named list including ggplot2 objects, as well as output printed to console.
