Loglikig {ig}R Documentation

Loglikelihood function associated to the inverse Gaussian type distribution

Description

Compute the loglikelihood function associated to the inverse Gaussian type distribution.

Usage

Loglikig(x, kernel = "normal", nu.fixed = 2)

Arguments

x Vector of observations.
kernel Kernel of the pdf of the associated symmetrical distribution by means of which the IGTD is obtained. The kernels: "Laplace", "logistic", "normal" and "t" are available.
nu.fixed Additional parameter of the IGTD when the t kernel is used.
