EnsBrier {SpecsVerification}

Calculate the ensemble-adjusted Brier Score

Description

Calculate the ensemble-adjusted Brier Score

Usage

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

FairBrier(ens, obs)

Arguments

ens

a N*R matrix representing N time instances of R-member ensemble forecasts of binary events; ens[t,r]=1 if the r-th ensemble member at time t predicted the event, otherwise ens[t,r]=0

obs

a numeric vector of length N with binary observations; obs[t]=1 if the event happens at time t, otherwise obs[t]=0

R.new

ensemble size for which the scores should be adjusted

Details

'FairBrier(ens, obs)' returns 'EnsBrier(ens, obs, R.new=Inf)'

Value

numeric vector of length N with the ensemble-adjusted Brier scores
