dot-modelfit function

Fit function when model object is given

Use update function to refit model and extract info such as coef, logLik and estfun.

.modelfit(model, data, coeffun = coef, weights, control, parm = NULL)

Arguments

• model: model object.
• data: data.
• coeffun: function that takes the model object and returns the coefficients. Useful when coef() does not return all coefficients (e.g. survreg).
• weights: weights.
• control: control options from ctree_control.
• parm: which parameters should be used for instability test?

Returns

A function returning a list of - coefficients: coef.

• objfun: logLik.

• object: the model object.

• converged: Did the model converge?

• estfun: estfun.
