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
