Cure-Rate Logistic-CoxPH Regression Object

Description

This class of objects is returned by the cureph class of functions to represent a fitted cure-rate logistic-CoxPH model. Objects of this class have methods for the functions summary and survpred.

Arguments

coefficients

the vector of coefficients. If the model is over-determined there will be missing values in the vector corresponding to the redundant columns in the model matrix.

var

the variance matrix of the coefficients. Rows and columns corresponding to any missing coefficients are set to zero.

loglik

the log-likelihood with the final values of the coefficients.

baseline

the step-function for baseline cummulative hazard.

wald.test

the Wald test of whether the final coefficients differ from the initial values.

iter

number of iterations used.

means

vector of column means of the X matrix. Subsequent survival curves are adjusted to this value. Factors are set to be the baseline level.

n

the number of observations used in the fit.

nevent

the number of events (usually deaths) used in the fit.

method

the computation method used.

na.action

the na.action attribute, if any, that was returned by the na.action routine.

...

The object will also contain the following: terms.logistic, terms.cox, assign.logistic, assign.cox, df, var.levels, formula.logistic, formula.cox, contrasts.logistic, contrasts.cox, call, data, Y, origin and end.
