Hi,
I'm tying to fit a glm using quasi with variance=mu(1-mu) (to try and  
get "well behaved" residuals). I get an error message:
"cannot find valid starting values, please specify some".
I have tried using start= and specifying coefficients from a previous  
fit (with different error structure) but get the same message.
What would be valid starting values?

I am using a 64 bit build R on a MacG5.

Thanks
