Returns an object of class "summary.feglm"
which is a list of summary statistics of

.
an object of class "feglm"
.
the type of covariance estimate required. "hessian"
refers to the inverse
of the negative expected Hessian after convergence and is the default option.
"outer.product"
is the outer-product-of-the-gradient estimator,
"sandwich"
is the sandwich estimator (sometimes also refered as robust estimator),
and "clustered"
computes a clustered covariance matrix given some cluster variables.
a symbolic description indicating the clustering of observations.

Multi-way clustering is done using the algorithm of Cameron, Gelbach, and Miller (2011). An example is provided in the vignette "Replicating an Empirical Example of International Trade".
