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)
