  ...
)

Arguments

model	A coxph object.
model_name	A name to be given to the PMML model.
app_name	The name of the application that generated the PMML.
description	A descriptive text for the Header element of the PMML.
copyright	The copyright notice for the model.

Details

A coxph object is the result of fitting a proportional hazards regression model, using the coxph function from the package survival. Although the survival package supports special terms "cluster", "tt" and "strata", only the special term "strata" is supported by the pmml package. Note that special term "strata" cannot be a multiplicative variable and only numeric risk regression is supported.
