dinvgauss: Inverse Gaussian pdf

In ActuDistns: Functions for actuarial scientists

Description

Computes the pdf of the inverse Gaussian distribution

Usage

dinvgauss(x, alpha = 1, sigma = 1)

Arguments

x	scale or vector of positive values at which the pdf needs to be computed
alpha	the value of alpha parameter, must be positive
sigma	the value of sigma parameter, must be positive

Value

An object of the same length as x, giving the pdf values computed at x

Note

If incorrect values are input for x or the model parameters then NaNs will be returned as the output. This function uses the R contributed package SuppDists.
