Use update function to refit model and extract info such as coef, logLik and estfun.
.modelfit(model, data, coeffun = coef, weights, control, parm = NULL)model object.
data.
function that takes the model object and returns the coefficients. Useful when coef() does not return all coefficients (e.g. survreg).
weights.
control options from ctree_control.
which parameters should be used for instability test?
A function returning a list of
coef.
logLik.
the model object.
Did the model converge?
estfun.
