...package GAM with more than one predictor? Changing lwd parameter in plot function controls all line components, including points making them thicker as well, which is not what I would like to have. Thanks for help.

Hi, I am performing glm with binomial family and my data show slight overdispersion (HF<1.5). Nevertheless, in order to take into account for this heterogeneity though weak, I use F-test rather than Chi-square (Krackow & Tkadlec, 2001). But surprisingly, outputs of this two tests are exactly similar. What is the reason and how can I scale the output by overdispersion ??
