Build a Normal probability plot with simulated envelope for a deviance-type residuals in semiparametric or multiple linear generalized log-gamma regression models.
envelope.sglg(fit, Rep)
fit |
an object of the class sglg. This object is returned from the call to glg(), sglg(). |
Rep |
a positive integer. This is the number of replications on which to build the simulated envelope. Default is Rep=50. |
