(default), the vector of
all random effects is returned (as used internally). However, for
random intercepts of type="car"
, the number of parameters is
one less than the number of regions and the indk = 2
is the classical AIC.coef
returns all estimated (regression)
parameters from a model as propsed by Paul and Held (2011), see
hhh4
.
If the model includes random effects, those can be extracted with
ranef
, whereas fixef
returns the fixed
parameters. The function AIC
returns the value of the AIC criterion
only for models without random effects, and returns NULL
in
the case of a random effects model where AIC is problematic.
The function logLik
returns an object of class "logLik"
in the case of a model without random effects, and the value of the
penalized log-likelihood at the parameter estimates otherwise.
The function confint
returns Wald-type confidence intervals
(assuming asymptotic normality)
for one or more parameters in the fitted model.
