LogLogistic: Log-logistic Curve constructor function

In gestate: Generalised Survival Trial Assessment Tool Environment

Log-logistic Curve constructor function

Description

This creates a Curve object for a Log-logistic distribution.
Curve objects contain all necessary information to describe a distribution, including functions and parameters describing it.
See Details for information on parameterisation.

Usage

LogLogistic(theta, eta)

Arguments

theta	Scale parameter for Log-logistic distribution.
eta	Shape parameter for Log-logistic distribution.

Details

The log-logistic distribution has parameterisation:
f(x) = eta (theta^beta) x^(eta-1) (theta^eta + x^eta)^-2
F(x) = (x^eta) /(theta^eta+x^eta)
