response
The name of the response vector (as a length-one character
vector), or a formula, giving a symbolic description of the model to be
fitted. When response
is a formula, it is used in preference to other
parameters to set the response
, features
, and intercept
parameters (if available). Currently, only simple linear combinations of
existing parameters is supposed; e.g. response ~ feature1 + feature2 + ...
.
The intercept term can be omitted by using - 1
in the model fit.
censor
The name of the vector that provides censoring information.
This should be a numeric vector, with 0 marking uncensored data, and
1 marking right-censored data.
