crps.circ {verification}R Documentation

CRPS Statistics for circular data

Description

Computes the circular CRPS when the verifying direction is 'x' and the probabilistic forecast is a von Mises distribution on the circle with mean 'mu' and concentration parameter 'kappa'.

Usage

crps.circ(x, mu, kappa )

Arguments

x

A single direction in angles (0 <= x < 2 pi)

mu

A single direction in angles (0 <= mu < 2 pi)

kappa

A single positive number (kappa >= 0)

Value

crps.circ

Circular crps
