[R] Inverse Gaussian dist in a GEE model

[René Holst]

For a simulation study, I need to fit a GEE with a IG distribution and using a log link function. As far as I know, there are two GEE packages available ('gee' and 'geepack') but none of them supports IG. I've also tried using family=quasi("log","mu^3") (without luck!).'
Any guidance is highly appreciated
 
Cheers,
 
René
