EnsCrps: Calculate the ensemble-adjusted Continuous Ranked Probability Score (CRPS)

Description

Calculate the ensemble-adjusted Continuous Ranked Probability Score (CRPS)

Usage

EnsCrps(ens, obs, R.new = NA)

FairCrps(ens, obs)

Arguments

ens

a N*R matrix representing N time instances of real-valued R-member ensemble forecasts

obs

a numeric vector of length N with real-valued observations

R.new

positive number, can be `Inf`, ensemble size for which the scores should be adjusted, default is NA for no adjustment

Value

numeric vector of length N with the ensemble-adjusted CRPS values

Details

`FairCrps(ens, obs)` returns `EnsCrps(ens, obs, R.new=Inf)`
