[R] link function
Hi everyone, I have a model which yields a qqnorm plot (residuals~fitted values) of a sigmoidal shape. I have been reading about link functions and leafing through Crawley, but I'm still not sure how to solve this. Perhaps "family=quasi(power=" is the best route? Any suggestions much appreciated.

Re: [R] Link to useR! 2006 from ww.r-project.org not working
Yes, this has been reported to the webmasters (not really much point in telling a list). cran.r-project.org and www.r-project.org now point at machines at wu-wien.ac.at (the DNS was changed in the last 24 hours). I have also found that rsync is not being allowed through (e.g. for tools/rsync-recommended) and ftp cannot see the R data area. Doubtless it will all be back to normal in a day or two.

Probably lost during the move of CRAN master. For the meantime use

[R] link between arima and arma fit

I am wondering why the fit of the time serie x with an arima and the fit of
diff(x) with an arma (same coeff p & d) differ one from another
here are the output of R:

arma(x = diff(x), order = c(7, 5))

What method between the two should be considered the best one?
Thanks for your help

[R] Link two variables
Hi. How can i link two variables, so when i group the first i group also the second one? I try whit create a model matrix (model.matrix) and use a grouping function like "balancedGrouped(nlme)". More specific i have varx:AGE and vary(binomial):o (dead),1(alive). I want to create age group,link vary group, compute the mean of x link the mean of y. Thank you.

Similar descriptions are also in "Modern Applied Statistics with > S-plus". Well, no choice of link is allowed in S-PLUS (sic), the subject of the book you mention. The R help file for gaussian() is wrong, and I will correct it. "inverse", "log" and "identity" links are allowed in the R code. This has been so since the current CVS file started in March 1998. > But the application of log link to gaussian family seems to be valid > in R. Note that it is quite possible for no MLE to exist in that case, so use with care: the symptom will be convergence problems, but they can occur even if there is a valid solution. -- Brian D.

[R] link function for gaussian family
Dear All, Is it possible to apply "log" link to gaussian family in glm? Help file saids that the gaussian family has only one permissible link, "identity". Similar descriptions are also in "Modern Applied Statistics with S-plus". But the application of log link to gaussian family seems to be valid in R. Thanks for any help.
