Beta-type prior for GP shape parameter \(\xi\)

For information about this and other priors see set_prior.

Usage

gp_beta(pars, min_xi = -1/2, max_xi = 1/2, pq = c(6, 9), trendsd = 0)

Arguments

pars

A numeric vector of length 2. GP parameters (\(\sigma, \xi\)).

min_xi

A numeric scalar. Prior lower bound on \(\xi\).

max_xi

A numeric scalar. Prior upper bound on \(\xi\).

pq

A numeric vector of length 2. See set_prior for details.

trendsd

Has no function other than to achieve compatibility with function in the evdbayes package.

Value

The log of the prior density.
