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.
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.
the variance matrix of the coefficients. Rows and columns corresponding to any missing coefficients are set to zero.
the log-likelihood with the final values of the coefficients.
the step-function for baseline cummulative hazard.
the Wald test of whether the final coefficients differ from the initial values.
number of iterations used.
vector of column means of the X matrix. Subsequent survival curves are adjusted to this value. Factors are set to be the baseline level.
the number of observations used in the fit.
the number of events (usually deaths) used in the fit.
the computation method used.
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.
cureph, summary.cureph, survpred.cureph.
