hhjorth: Log Hazard Function for a Hjorth Process

In swihart/event: Event History Procedures and Models

Description

These functions provide information about the Hjorth distribution with location parameter equal to m, dispersion equal to s, and family parameter equal to f: log hazard. (See 'rmutil' for the d/p/q/r boxcox functions density, cumulative distribution, quantiles, and random generation).

The Hjorth distribution has density

f(y) = (1+s y)^(-f/s) exp(-(y/m)^2/2) (y/m^2+f/(1+s y))

where m is the location parameter of the distribution, s is the dispersion, and f is the family parameter.

Usage

hhjorth(y, m, s, f)

Arguments

y	vector of responses.
m	vector of location parameters.
s	vector of dispersion parameters.
f	vector of family parameters.
