Function assesses whether the inputs correspond to the requirements for scoring sample-based forecasts.

Usage

check_input_sample(observed, predicted)

Arguments

observed

Input to be checked. Should be a numeric vector with the observed values of size n.

predicted

Input to be checked. Should be a numeric nxN matrix of predictive samples, n (number of rows) being the number of data points and N (number of columns) the number of samples per forecast. If observed is just a single number, then predicted values can just be a vector of size N.

Value

Returns TRUE if the check was successful and a string with an error message otherwise.
