Dear Allstat
We have had a paper returned to us for amendment. One reviewer invited us to include R^2 values for our glm's (which had continuous outcome variables). The output of our software (R-glm) includes values for residual deviance and null deviance. I have seen mention of a pseudo-R^2 calculated as 1-(residual deviance/null deviance). Would it be reasonable to use such an approach in our case? If so, I would be grateful for a reference to such an approach.
Thanks
