modelparm(model, coef., vcov., df, ...)
coef
and vcov
methods
for arbitrary models to
return a vector of $p$ fixed effects model parameters (coef
)
and corresponding $p vcov
). The coef.
and vcov.
arguments can be used to define
modified coef
or vcov
methods for a specific model.
Methods for lmer
and survreg
objects are available (internally).
For objects inheriting from class lm
the degrees of
freedom are determined from model
and the corresponding
multivariate $t$ distribution is used by all methods to glht
objects. By default, the asymptotic multivariate normal distribution
is used in all other cases unless df
is specified by the user.
