This function computes the goodness-of-fit test statistic for the gamma family in the spirit of Watson. Note that this tests the composite hypothesis of fit to the family of gamma distributions, i.e. a bootstrap procedure is implemented to perform the test, see crit.values

The Watson test is computed as described in Henze et. al. (2012). Values of k_estimator
are found by gamma_est
