Beta quantile function

Description

Computes the quantile function of the beta distribution

Usage

1
qbetad(x, u = 0.5, a = 1, b = 1)

Arguments

x

scale or vector of values at which the integrated hazard rate function needs to be computed, values must be in the unit interval

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

a

the value of b parameter, must be positive

b

the value of nu 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.
