Calculate the MLE of the Gamma Dispersion Parameter in a GLM Fit

Description:

     A front end to 'gamma.shape' for convenience.  Finds the
     reciprocal of the estimate of the shape parameter only.

Usage:

     gamma.dispersion(object, ...)

Arguments:

  object: Fitted model object giving the gamma fit. 

     ...: Additional arguments passed on to 'gamma.shape'. 

Value:

     The MLE of the dispersion parameter of the gamma distribution.
