I'm forwarding this to the R-sig-geo list to see if some other user of the
off-CRAN Dcluster package who may be able to help - it is also possible to
write to the package maintainer directly.

Subject: [R] bootstrap pValue in DClusters
I use DClusters package (I work in a cancer regestry). I have 2 questions
1-how is it possible to get back the bootstrap pValue? I mean the pValue of
the calculated statistic with respect of the distribution of this statistic
under the null hypothesis.
2-how is it possible to test an overdispersion in the poisson model? for
choosing a best model I need this mesure of dispersion. Should I build a
glm(cases~expected,family=quasipoisson)$sig2 or is it possible directly in
Thank you, for advance for answers. Best regards, Erik A.
