similar to: Re: Clinical Significance as a package

Hi, Many thanks to those of you who responded to my last post about Schafer's MI packages. I am really pleased to have access to them through R which, I have to say, is an amazing piece of software. I am only sorry that I haven't found it until now. But, to my question. Does anyone know if there is a package developed for evaluating clinical significance using Jacobson and Truax's,

From a quick look at the paper in the SAS proceedings, the simulations seem limited to nested designs. The major problems are with repeated measures designs where the error structure is not compound symmetric, which lme4 does not at present handle (unless I have missed something). Such imbalance as was investigated was not a serious issue, at least for the Kenward and Roger degree of freedom

A point of clarification. The "get started video" on asterisk.org says that running asterisk on a virtual platform is a popular option. "Go for it!" the presenter says. However, the 2011 third edition of Asterisk, The Definitive Guide says they don't recommend it for production use, though many do so successfully. I also don't find may recent discussions of this

I'm using R on Windows v2.0.1 with the nlme package (v3.1-53) and am finding some unexpected discrepancies in the output of intervals.lme and coef.lme. I've included a toy dataset at the end, but briefly, the data are longitudinal data from couples in marital therapy. Each spouse's relationship satisfaction is measured 4 times; I've fit both linear and quadratic models to the

I am interested to use plotmath functions within a panel function but am having some problems getting the code right. Within each panel I am plotting the data, fitting a regression line, and would like to print the regression equation. Here is a trivial example of what I'd like to do: # generate simple data tmp.df <- data.frame(id = rep(1:4, each=4), time = rep(1:4, 4), das =

Background: Our research group collected data from students via the web about their drinking habits (alcohol) over the last 90 days. As you might guess, some students seem to have lost interest and completed some information but not all. Unfortunately, the survey was programmed to "pre-populate" the fields with zeroes (to make it easier for students to complete). Obviously, when

Hi all-- I am in the process of helping colleagues write up a ms in which we fit zero-inflated Poisson models. I would prefer plotting the rate ratios and 95% CI (as I've found Gelman and others convincing about plotting tables...), but our journals usually like the numbers themselves. Thus, I'm looking at a recent JAMA article in which both numbers and dotplot of RR and 95% CI are

Hi all-- We are planning an intervention study for adolescent alcohol use, and I am planning to use simulations based on a hurdle model (using the hurdle() function in package pscl) for sample size estimation. The simulation code and power code are below -- note that at the moment the "power" code is just returning the coefficients, as something isn't working quite right. The

I'm attempting to use xyplot() within a for() loop to plot the relationship between a DV and a series of predictor variables, split by 2 conditioning variables. However, xyplot() does not "seem" to be recognized within the for() loop; I don't receive any error message, but nothing is plotted and a plotting device is not opened. When I use the generic function plot(),

Hi all, I'm new to rsync and have a problem I cannot resolve even after plowing through the lists. I have an rsync server setup with an rsync client. I am trying to backup a directory structure that is over four levels deep. Rsync does great until it hits that fourth level. Then it errors out for each file in that fourth level similar to this: rsync: recv_generator: mkdir

Hello, I have two production servers which house large drive arrays storing digitized music for our webradio. They are used in a 'failover' configuration so that if one goes down the other remains available. New music is added all of the time to this library and it is a pain to have to add it to both machines as the files are large (.wav). I am thinking to setup rsync to keep the drives

We have been running Icecast for quite a while (over a year) on a windows platform. No problems there. Last week we switched over to Fedora. On the windows platform, the *auth files were in the root of the icecast install directory along with icecast.xml and the binary. On *nix the binary is in /usr/local/bin while the icecast.xml is in /etc. So, I moved the *auth files to the /etc and the

Hi all, I decided the best way to get to know * well is to do it from scratch. Having read the majority of the "Asterisk: The Future of Telephony" I am now attempting to compile zaptel 1.4.0 and am receving the very same series of errors mentioned in this post on the forums: http://forums.digium.com/viewtopic.php?t=13619&highlight=zaptel1+++zttranscode++error However, there has

Back in the Fedora docs I found on a google, it mentions that in FC6, the preferred tool for updates was the "new" yum-updatesd. Anyone know: a) what theological reason upstream had to drop it altogether, and b) what's the recommended replacement - is it yum-cron? I hand-update some servers, and of course users' workstations, but some system, like home directory servers and

I used both BMDP and SAS in my earlier years, side by side. At that time the BMDP statistical methods were much more mature and comprehensive: we treated them as the standard when the two packages disagreed. (It was a BMDP manual that clearly explained to me what the hypothesis of "Yate's weighted mean test" is, something SAS decided to call "type III" and eternally

Dear All, I am looking an R version of the "Computer program for sample size and power calculations in the design of multi-arm and factorial clinical trials with survival endpoints". Best regards, Giovanni Parrinello P.S.: in the meantime I am preparing a summary for my preceeding question about time-varying covariates in the Cox model and I thank Frank Harrell, Chuck Cleland,

We are finding more and more clinical researchers interested in learning R and are starting to teach R to clinicians. We have put some teaching material on our site: http://biostat.mc.vanderbilt.edu -- Frank E Harrell Jr Professor and Chair School of Medicine Department of Biostatistics Vanderbilt University

Is anybody using R to do analysis of clinical trial datasets that have been put in the public domain (which are super hard to find). Not only a single data table, but the actual database, with a handful of data tables with one-to-one or many-to-one relationships? [ For example, "Adverse Events" and "Patient Info" are two datasets with a many-to-one relationship, the
