Gompertz {gestate}

Gompertz Curve constructor function

Description

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

Usage

Gompertz(theta, eta)

Arguments

theta

Scale parameter for Log-logistic distribution.

eta

Shape parameter for Log-logistic distribution.

Details

The Gompertz distribution has parameterisation:
f(x) = theta eta e^(eta + theta x - eta e^(theta x))
F(x) = 1 - exp(eta - eta e^(theta x))
