further arguments passed to or from other methods. |
The argument supplied to dispersion
must be either 1
(location model) or 2 (scale model). The reason for this is because
the fitting of the model has already
scaled the covariance matrix for the location coefficients. Hence the
scaled and unscaled versions of covariance matrix for the location
model are identical.
This function will not be generally called by the user as it
will only summarize the location or scale model but not both. Instead
the user should refer to summary.tlm
to print a summary of both models.
