vcov.autologistic: Return the estimated covariance matrix for an autologistic model object.
Description
Return the estimated covariance matrix for an
autologistic model object.
Usage
## S3 method for class 'autologistic':
vcov(object, ...)
Arguments
object
a fitted autologistic model object.
...
additional arguments.
Value
An estimate of the covariance matrix of the parameters
(in a Bayesian setting), or an estimate of the covariance
matrix of the maximum pseudolikelihood estimator of the
parameters. The latter requires a bootstrap sample. If
there is no such sample, NULL is returned.
