Assert that inputs are correct for sample-based forecast

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

Usage

assert_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 NULL invisibly if the assertion was successful and throws an error otherwise.
