Generic Accessor Function for Model Parameters
Extract model parameters and their covariance matrix as well as degrees of freedom (if available) from a fitted model.
modelparm(model, coef., vcov., df, ...)
- a fitted model,
for example an object returned by
- an accessor function for the model parameters.
- an accessor function for the covariance matrix of the model parameters.
- an optional specification of the degrees of freedom to be used in subsequent computations.
- additional arguments, currently ignored.
One can't expect For objects inheriting from class
for arbitrary models to

multivariate $t$ distribution is used by all methods to
objects. By default, the asymptotic multivariate normal distribution
is used in all other cases unless
df is specified by the user.
