Re: [R] dreaded p-val for d^2 of a glm / gam

I assume you mean 'deviance', not 'squared deviance'; if the latter, then I have no idea. If the former, then a short and fairly quick answer to your question is that 2*log(likelihood ratio) for nested hypotheses is approximately chi-square with numbers of degrees of freedom = the
