s_loglogistic: Factory of SURVIVAL objects with Log Logistic distributions

In survobj: Objects to Simulate Survival Times

Factory of SURVIVAL objects with Log Logistic distributions

Description

Creates a SURVIVAL object with a Log Logistic distribution.

Usage

s_loglogistic(...)

Arguments

...	Parameters to define the distribution. See the Parameters for details

Value

a SURVIVAL object of the log-logistic distribution family. See the documentation of s_factory for the methods available for SURVIVAL objects

Parameters

To create an exponential survival object the following options are available:

scale and shape to specify the canonical parameters of the distribution, or

surv, t and shape for the proportion surviving (no events) at time t and the shape parameter, or

fail, t and shape for the proportion failing (events) at time t and the shape parameter or

intercept and scale for the parameters returned by survreg(.., dist = "loglogistic") models.

The parameters should be spell correctly as partial matching is not available

Examples

s_loglogistic(scale = 2,shape = 2)
s_loglogistic(surv = 0.6, t= 12, shape = 0.5)
s_loglogistic(fail = 0.4, t = 12, shape =0.5)
s_loglogistic(intercept = 0.4, scale = 0.5)
