| survreg.object {survival} | R Documentation |
This class of objects is returned by the survreg function
to represent a fitted parametric survival model.
Objects of this class have methods for the functions print,
summary, predict, and residuals.
The following components must be included in a legitimate survreg object.
linear.predictors, which multiply the
columns of the model
matrix.
It does not include the estimate of error (sigma).
The names of the coefficients are the names of the
single-degree-of-freedom effects (the columns of the
model matrix).
If the model is over-determined there will
be missing values in the coefficients corresponding to non-estimable
coefficients.
The object will also have the following components found in
other model results (some are optional):
linear predictors, weights, x, y, model,
call, terms and formula.
