get_accuracy: get_accuracy

In AlbyDR/rSCOPE: Run SCOPE model through R

get_accuracy

Description

This is a function to get the predictions for a specific output simulated by SCOPE and calculate the accuracy.

Usage

get_accuracy(
  obs_vec,
  predictions,
  metric_function,
  Filter = FALSE,
  timestamp,
  month_start = 1,
  month_end = 12,
  period = c("day", "dawn_dusk", "night"),
  nu_interations,
  interations = 101,
  dryhours_vec,
  dry_hours = 0,
  neg_vec,
  neg_null = 0,
  pred_neg = 0,
  neg_values = NA,
  lat = 52.46,
  lon = 13.32
)

Arguments

obs_vec	for get_accuracy a vector of observed values in the same timestamp as the predictions.
predictions	the name of the file result of the get_predictions function.
metric_function	for get_accuracy is possible to select the metric,

Value

The result is a table with the accuracy metrics for all simulation starting with that name.
