Robust Standard Error for Regression Parameters

Compute robust standard error for regression parameters in the context of clustered observations for an object of mcglm class.

mc_robust_std(object, id)

Arguments

object	an object of mcglm class.
id	a vector which identifies the clusters or subject indexes. The length and order of id should be the same as the number of observations. Data are assumed to be sorted so that observations on a cluster are contiguous rows for all entities in the formula.
