Re: [R] glm(quasipoisson) with non-integer response

[aoxbrough]

Hi,

I realise this was a few years ago, but any chance you could pass on the
help page that give references for this?

I have the same issue with my own data at present (noninteger count data). 

Many thanks,

Anne Oxbrough

 Hi,

 I have count data that have been meddled with enough to make them non
 integers. Using glm(poisson) returns a non integer error but
 glm(quasipoisson) does not. Just wondering if anyone knows if I am
 violating the assumptions of a quasipoisson error structure by using
 these non-integer response data?

No, it just assumes variance \propto mean.

 Thanks! I'd welcome your thoughts and/or references...
