bgev (version 0.2)

likbgev: Log likelihood function for the bimodal GEV distribution.

Description

Uses the density function to evaluate the likelihood. This is useful for the 'bgev.mle' function.

Usage

likbgev(y, theta = c(1, 1, 0.3, 2))

Value

a unidimensional vector containing the computed log likelihood for y.

Arguments

y

a unidimensional vector containing the points to compute the log likelihood

theta

bimodal GEV parameters as an ordered pair theta = (mu,sigma,xi,delta)

Examples

# get random points from bimodal GEV
y = rbgev(100, mu = 1, sigma = 1, xi = 0.3, delta = 2)
