log_logLogistic {bayesCureRateModel}

PDF and CDF of the log-Logistic distribution.

Description

The log-Logistic distribution as evaluated at the flexsurv package.

Usage

log_logLogistic(y, a1, a2, c_under = 1e-09)

Arguments

y

observed data

a1

shape parameter

a2

scale parameter

c_under

A small positive value corresponding to the underflow threshold, e.g. c_under = 1e-9.

Details

The log-logistic distribution is the probability distribution of a random variable whose logarithm has a logistic distribution.

Value

A list containing the following entries
