EITrans::optimize_parameters carries out a search for the optimized parameter combination for EITrans calibration with the input training ensembles forecasts and observations.

optimize_parameters(grid_search, ens_train, obs_train, verbose = F)

Arguments

grid_search

A data frame with columns left_deltas, right_deltas, left_infinity, right_infinity, and multiplier.

ens_train

A 4-dimensional array as training ensemble forecasts. Dimensions should be [stations, times, lead times, members].

obs_train

A 3-dimensional array for observations that correspond to the ensemble forecasts. Dimensions should be [stations, times, lead times].

verbose

Whether to print progress information.

Value

A list with member offsets calculated with each of the parameter combination and the rank histogram of the calibrated training forecast ensemble with the corresponding parameter combination.
