Additional methods which can simplify working with the GEE result object.
# S3 method for tern_gee
VarCorr(x, sigma = 1, ...)# S3 method for tern_gee
QIC(object, ...)
VarCorr() returns the estimated covariance matrix, and
QIC() returns the QIC value.
(tern_gee)
result of fit_gee().
an optional numeric value used as a multiplier for the
standard deviations. The default is x$sigma or 1
depending on class(x).
further optional arguments passed to other methods (none for the methods documented here).
(tern_gee)
result of fit_gee().
