Dear R users, I would like to fit cross classified or multiple membership logistic models or a 3 level hierarchical logistic model using the Umacs package. Can anyone advise me on how to proceed or better point me to examples of how its done.

Dear R-users, I would like to fit a glmm with cross-classified random effects with the function MCMCglmm. Something along the lines: model1<-MCMCglmm(response~pred1, random=~re1+re2, data=data) where re1 and re2 should be crossed random effects. I was wondering whether you could tell me specifying cross-classified random effects in MCMCglmm requires a particular syntax? Are there any

Hi All, I''m not convinced I have my tcrules correctly setup and looking at the counters in the mangle table''s tcpost doesn''t really help much as I can''t tell what is the final match. Is there a way to match packets in iptables based on the classifier? i.e. so I can LOG packets classified with 1:18 for example. I can''t see anything in iptables, except

Dear All, The "coxph" function in the "survival" package allows multiple frailty terms. In all the examples I saw, however, the frailty terms are nested. What will happen if I have non-nested (that is, cross-classified) frailties in the model? Will the model still work? Do I need to take special cares when specifying these models? Thanks!

Hello, this is probably a dumb question, but I can't for the life of me figure out why sendmail and courier are classified universally as network-mail-mta whereas dovecot is in places like network-mail-general or some such place. I've used several Linux distros and have noted this keenly (they also normally classify photorec, the HD recovery tool as hardware-photography,so this may just be

I''m new to RoR and going through the tutorials trying to learn as much as possible. I have actually two questions: 1. What is a proper way to deploy an app into the PROD environment? Here is what I''m trying to avoid: when writing/testing application (ie. new user signs ups) on my local machine, I don''t want these users to be deployed into the PROD environment along

Hello all: I am in the process of redesigning my site and was thinking about incorporating RoR into the overall structure. However, there are multiple things I would like to create with Rails, namely a gallery, a weblog, and portfolio management system. Given that I am going to be using a lot of RoR, what is the best way to accomplish this task? Here are some random things that have come

Dear R-Users, I have fitted a cross-classified generalized linear mixed model using the lmer package with the following code. Mod<-lmer(y~x+(1|a)+(1|b)+ (1|c), family=binomial) In this case, only including a covariate (x) as a fixed effect. The fitted values, using fitted(mod), correspond to the raw data nicely, and the mean of the fitted values is equal to the mean of the raw data. In

This is a question about how to calculate similarities/distances among items that are classified by hierarchical attributes for the purpose of visualizing the relations among items by means of clustering, MDS, self-organizing maps, and so forth. I have a set of ~260 items that have been classified using two sets of hierarchically-organized codes on the basis of form and content. The data looks

All, I have several years of longitudinal test scores for students (many who switch schools at various points in time). I am using a mixed-effects model with crossed random effects to model student trajectories. The model includes time at level 1 and students crossed with schools at level 2. When I run the model I get the posterior variances on the intercepts and slopes for students and schools,

Enlightenment succeeded! Thanks, David

On page 165 of Mixed-Effects Models in S and S-Plus by Pinheiro and Bates there is an example of using lme() in the nlme package to fit a model with crossed random factors. The example assumes though that the data is grouped. Is it possible to use lme() to fit crossed random factors when the data is not grouped? E.g., y <- rnorm(12); a=gl(4,1,12); b=gl(3,4,12). Can I fit an additive model
