Continuous Ranked Probability Score (CRPS)

Usage

metric_CRPS(dat, ...)

Arguments

dat

dataframe with column `obvs` and either an `ensemble_matrix` attribute, wide ensemble member columns (`member_1`, `member_2`, ...), or matrix column `model_ensemble`.

...

ignored

Value

A numeric value representing the mean CRPS across observations.

Details

Computes the Continuous Ranked Probability Score (CRPS) to evaluate model uncertainty and ensemble skill against observation data. Uses `scoringRules::crps_sample()` when available, with a pure R analytical sample score fallback when `scoringRules` is not present.
