In bayesCureRateModel: Bayesian Cure Rate Modeling for Time-to-Event Data

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

log_f	natural logarithm of the pdf, evaluated at each datapoint.
log_F	natural logarithm of the CDF, evaluated at each datapoint.
