glm() for log link and Weibull family
...orensic samples from surfaces, where as much powder as possible is collected. This apparently causes the results to conform to some type of extreme value distribution, so Weibull is a reasonable starting point for exploration. I have tried ('surface' and 'team' are factors) glm(surfcount ~ surface*team, data=powderd, family=Gamma(link='log')) but this doesn't quite do the trick. The standardized deviance residuals are still curved away from normal at the tails. Thanks for any info you can give on this nonstandard model. ===============================================...
