Check Prediction Input For Lower-level Scoring Functions — check

Helper function to check inputs for lower-level score functions.

Usage

check_predictions(
  predictions,
  true_values = NULL,
  type = c("continuous", "integer", "binary"),
  class = c("vector", "matrix")
)

predictions: an object with predictions. Depending on whether class = vector or class = "matrix" this can be either a vector of length n (corresponding to the length of the true_values) or a nxN matrix of predictive samples, n (number of rows) being the number of data points and N (number of columns) the number of Monte Carlo samples
true_values: A vector with the true observed values of size n
type: character, one of "continuous" (default), "integer" or "binary" that defines the type of the forecast
class: character, either "vector" (default) or "matrix" that determines the class the input has to correspond to
