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.
