similar to: appending data to a row

Dear R users I am analysing data from a group of twins and their siblings. The measures that we are interested in are all correlated within families, with the correlations being stronger between twins than between non-twin siblings. The measures are all calculated from survey answers and by definition have limited ranges (e.g. -5 to +5), though within the range they are approximately normally

Can anyone shed any light on this? > doubt.demographic.pql<-glmmPQL(random = ~ 1 | groupid/participantid, + fixed = r.info.doubt ~ + realage + minority + female + education + income + scenario, + data = fgdata.df[coded.resource,], + na.action=na.omit, +

Greetings- Using R 1.5.0 under linux and the latest MASS and nlme, I am trying to develop a three-level (two levels of nesting) model with a dichotomous oucome variable. The unconditional model is thus: > doubt1.pql<-glmmPQL(fixed = r.info.doubt ~ 1, random = ~1 | groupid/participantid, + family = binomial, data = fgdata.10statements.df) iteration 1 iteration 2 iteration 3 iteration 4

Greetings. I'm running some models under R using glmmPQL from MASS. These are three-level models (two grouped levels and the individual level) with dichotomous outcomes. There are several statistics of interest; for the moment, I have two specific questions: 1.) This question refers to the following model (I present first the call, then the output of summary():

Dear All: lme(sbp ~ cengirth, data = family, random= ~ 1 | familyid) converges but lme(sbp ~ cengirth, data = family, random= ~ cengirth | familyid) does not. I get the following message: Error in lme.formula(sbp ~ cengirth, data = family, random = ~cengirth | : iteration limit reached without convergence (9) The data has 488 rows and 154 familyid levels. For

Dear all, When calling rlm with the following data, I get an error.

Hi, Here you can find a list of MS Exchange 2007 compliant systems: http://www.microsoft.com/technet/prodtechnol/exchange/telephony-advisor.mspx You cannot see mention of Asterisk ;-)) Has anyone tried to "integrate" Asterisk and Exchange 2007 ? A prospective customer is using MS Exchange 2007 and is asking for such integration. Passion aside, what do you think of such integration ?

Hello everyone, I've added the "S" suffixed versions of ARM and Thumb2 instructions to tablegen. Those are, for example, "movs" or "muls". Of course, some instructions have already had their twins, such as add/adds, and I leaved them untouched. Besides, I propose the codegen optimization based on them, which removes the redundant comparison in patterns like orr

You can also download MS Visual C++ Toolkit 2003 - contains the VC++ 7.1 compiler/linker as well as all the standard libraries and headers. No gui, no debugger though:

Hi, i''m running a two dom0 nodes cluster for HA, and xen domUs running on top, currently it handles 5 domUs. The issue is that there''s a domU that can only run on one node, it''s not possible to start it on the other one. I get a ''b'' status and can''t access the console. Other domUs can start in either node and I can access their console without

Hi, Is anyone here using TwinView with NVIDIA graphics drivers under CentOS 5? Just tried this configuration (I've been using dual monitors as separate X screens in the past), and while it works in a sense, there are a few issue that will probably prevent me from using it for real. Notably, which screen new applications start on (when using the Applications menu or panel launchers) seems to

Hi people Just wondered what your thoughts are on Microsoft's RTAudio codec that they use in their Unified Communications stuff: http://www.microsoft.com/downloads/details.aspx?familyid=5D79B584-79C9-42A8-90C4-4AB3F03D19C4&displaylang=en They let people license it to use in their own products. I couldn't find any sample clips of RTAudio encoded speech. Apart from being $35000 less

This isn''t specific to RSpec, but is hopefully on-topic for this list. I like (especially when "ping pong pairing") to write a spec, then write the smallest amount of code I can to pass it (especially when "ping pong pairing"). Sometimes this means hard-coding a return value, which means another spec is needed to prove that the code is really behaving as it

Hi all, Has anyone got Animation:Master (preferably the 2004 version) working on Wine in Ubuntu? I know the AppDB lists Animation:Master 2005 rating as 'Garbage' because it requires the CD to run, but that hasn't been a problem for me. The program actually shows the splash screen and appears to load quite well, but when the main program window appears, there is no mouse cursor (it

Hello, I've searched for an answer to no avail. I am wondering if anyone knows how to constrain certain correlations to be equal. I have family data with 2 twins per family plus up to 2 siblings. I would like to somehow constrain all the sibling correlations (twin-sib and sib-sib) to be the same while allowing the twin-twin correlation to be different. Here is some simulated code:
