I've got a colleague who's using a GLMM to analyse her data, and I've told her that she needs to include an offset. However, glmmPQL doesn't seem to allow one to be included. Is there anyway of doing this? Bob -- Bob O'Hara Rolf Nevanlinna Institute P.O.

Dear all, I didn't find any graphical solution in the package "mva" to plot the canonical scores from a CCA (canonical correlation analysis). Does anybody knows how to plot or has anybody already programmed : - the map of the canonical scores, - the graph of the canonical weights, - the correlation circle i.e. the canonical loadings ? Thank you for help ...

...n R query, but you can probably see whats' coming... If you know the answer to the last question, then how do I sample from the distribution? Again, if it's a gamma/chi^2 then I already know, but if not... Thanks in advance! Bob -- Bob O'Hara Rolf Nevanlinna Institute P.O.

Moi! I have a problem where I want to find the ML estimate of a discrete parameter. I just want a function like optim that finds the max/min value for a function. Does anyone know of such a function for R? Thanks. Bob -- Bob O'Hara Rolf Nevanlinna Institute P.O.

Anybody know where I can get the Pinheiro/Bates book? I can't find a bookstore w/ stock and the publisher says they don't know when they'll have it again. Thanks. -Frank

...ecified for graphics parameter "fig". I get the same in R-1.8.1 on Windows, and R-1.5.1 on Linux.

...esn't this work now, and (b) what can I do about it? I've tried using simpler models, but only models with one or two main effects work, and this is no good for what I want.

Hi! I was trying to implement a probit model on a dichotomous outcome variable and found that the predictions were outside the (0,1) interval that one should get. I later tried it with some simulated data with a similar result. Here is a toy program I wrote and I cant figure why I should be getting such odd predictions. x1<-rnorm(1000) x2<-rnorm(1000) x3<-rnorm(1000)

...e thing happens. I assume that this is because for much of the range, the integral is basically zero. Can anyone suggest a fix? Preferably one that will work with Count=320 and Count=0 (both of which I have in the data). Bob -- Bob O'Hara Dept. of Mathematics and Statistics P.O.

...useless (because the null hypothesis is silly), at next worse you're just testing whether you have enough data to distinguish an effect from zero (because a priori the null hypothesis is merely unlikely to be true).
