crps.circ: 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

mu

A single direction in angles (0

kappa

A single positive number (kappa >= 0)

Value

• crps.circ
  Circular crps
