[R] QIC from gee() or geese()

[Richard Chandler]

Hello,

Is it possible to derive Pan's QIC (2001 Biometrics 57:120) from
either a fitted gee() object in the gee package or from a geese() fit
in the geepack package? If so, would anyone be kind enough to provide
me with code to do so? I realize that QIC is part of the output from
yags() but I would like to use one of the other functions. Thanks.

Richard
