Description

Computes the quantile function of the inverse Gaussian distribution

Usage

1
qinversegaussian(x, u = 0.5, alpha = 1, sigma = 1)

Arguments

x

scale or vector of positive values at which the integrated hazard rate function needs to be computed

u

scale or vector of positive values at which the integrated hazard rate function needs to be computed, must be of the same length as x

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 hazard rate function values computed at x and u

Note

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