"model.frame"(formula, ...)
"model.matrix"(object, par=NULL, ...)flexsurvreg.flexsurvreg. The default value of par=NULL returns a matrix consisting of
the model matrices for all models in the object cbinded
together, with the intercepts excluded. This is not really a
``model matrix'' in the usual sense, however, the columns directly
correspond to the covariate coefficients in the matrix of estimates
from the fitted model.
model.frame returns a data frame with all the original
variables used for the model fit.model.matrix returns a design matrix for a part of the
model that includes covariates. The required part is indicated by the
"par" argument (see above).
