qlai: Lai quantile function

In ActuDistns: Functions for actuarial scientists

Description

Computes the quantile function of the Lai distribution

Usage

qlai(x, u = 0.5, lambda = 1, beta = 1, nu = 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
lambda	the value of lambda parameter, must be positive
beta	the value of beta parameter, must be non-negative but both beta and nu cannot be zero
nu	the value of nu parameter, must be non-negative but both beta and nu cannot be zero

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 hypergeo.
