DressCrps: Calculate the Continuous Ranked Probability Score (CRPS) for a mixture of Normal distributions, for example generated by ensemble dressing

Description

Calculate the Continuous Ranked Probability Score (CRPS) for a mixture of Normal distributions, for example generated by ensemble dressing

Usage

DressCrps(dressed.ens, obs)

Arguments

dressed.ens

a list with elements `ens`, a N*R matrix representing N time instances of kernel centers, and `ker.wd`, a N*R matrix with corresponding kernel standard deviations. See function `DressEnsemble`

obs

a numeric vector of length N with real-valued observations

Value

numeric vector of length N with the CRPS values
