Multiple imputation with plausible values already in the data
...doing some secondary analyses of the PISA (http://pisa.oecd.org) student data. I would like to treat missing values properly, that is using multiple imputation (with the mix package). But I am not sure how to do the imputation, since the data set provided by the OECD already contains variables with plausible values. Roughly, the situation is like this: for each of the cognitive (achievement) scales, there are five variables holding plausible values. So for example, there is not one variable for math achievement, but five, pv1math through pv5math. There are, of course, no missing values on these variab...

A seemingly plausible userspace command submission model.
Please tell me what can't work about this idea. - Introduce concept of "batches", through some kind of marker (tied to fences). - Request buffers up front, userspace does all relocation (avoid teaching the kernel about tiling, etc). - Driver stores state for each batch. - FIRE_RING becomes an ioctl that can fail (imagine backgrounded app holding pinned memory for too long). ==>

UPS (Megatec) with strange voltage values
...battery value returned by F command. When power is lost, the 2.27V drops very quickly to 2.06V 2.06V x 6 = 12.36V Which seems to be correct for a 12V battery. To top it up, I command returns an empty string, which would help "a lot" to identify it. OK, my questions are: 1) Is 2.27V plausible for battery voltage or should it be 13,62V? 2) Is 240V plausible for battey nominal voltage or should it be 12V? 3) Wich can I consider battery full? 2.27V or 2.06V? 4) Any tips to solve this problem? Divide and multiply inside megatec driver? Is there any chance to some UPS hacks in megatec driver...

OFF TOPIC: chatGPT glibly produces a lot of wrong answers?

EL7 mirror: "There is no installed groups file."
...'t work, I decided to set up a local mirror. I rsync'd ftp://ftp.redhat.com/pub/redhat/rhel/beta/7/x86_64/os/Packages/ to a local web server here, then regenerated the repodata directory with createrepo. Now yum works fine, for the most part. "yum search foo" pulls up a plausible list of packages, "yum install bar" chases dependencies as expected, etc. Unfortunately, "yum groupinstall" isn't working, which means I have no easy way to install Gnome on my minimal EL7 installation. Apparently I need some kind of "groups file" to feed to c...

Preserving output of MCMC iterations
...ection that is mainly informed by actual field programme data. Basically, I have a set of four differential equations governing my model, which I am implementing stochastically (small populations, low transmission). I iterate the model a large number of times (10 000) for each unique combination of plausible values of the three unknown parameters a, b and c. After each iteration, I ask R to check whether the output 'fits' the observed data: if it does, I ask R to add 1 to the (i,j,k)th element of a 3-dimensional 'scores' array (3 unknown parameters = 3 dimensions), where i,j, and k are...

Survfit: why different survival curves but same parameter estimates?
Hello, I'm trying to estimate a Cox proportional hazard model with time-varying covariates using coxph. The parameter estimates are fine but there is something wrong with the survival curves I get with survfit (results are not plausible). Let me explain why I think something's wrong. To make sure I'm setting up my data correctly to estimate a model with time-varying covariates, I start with a model and data that only has constant covariates. I can then estimate this model with "model1 <- coxph(formula=Surv(y1, y2...

Calling dovecot-lda correctly from exim for virtual user setup
...command = HOME=/home/vmail/\$local_part /usr/lib/dovecot/dovecot-lda -f \$sender_address use_shell .. I.e. a command is executed via the shell, and Exim uses non-sanitized user input (mail header fields) to construct the command. Now, the reason I invoked dovecot like that is to pass a plausible value for the HOME environment variable, so that dovecot-lda can determine where the Maildir directory of the recipient is. Is there any way to achieve this without requiring HOME to be set correctly? I looked at the -m switch but as far as I can see that merely defines the destination mailbox...

meta-analysis question
Dear R-helpers, i have the following situation: i have a bunch of y=b0 + b1*x from different studies, and want to estimate a "general" y=f(x). I only have the b0,b1's and R-squareds. Should i weigh the separate equations by their R-squared? thanks Remko ^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~'^'~,_,~' Remko Duursma, Ph.D. student

[LLVMdev] Dependence Analysis
...yone. I've been examining llvm for a while and been duly impressed. I'd like to contribute in the area of dependence analysis, and a good place to start seems to be in the transformation of pointers to explicit array accesses. Is anyone else working on this? If not, does this seem a plausible place to start and how would be the best way to go about it? Thanks, Naftali

qt for df < 1
...on for estimating student t binary response models, tentatively called gossit, and I noticed eventually that the R qt function doesn't like df < 1. Vaguely recalling that Splus didn't seem to mind such weirdness, I checked on our soon to be defunct Splus6.2 and sure enough, it produced plausible answers instead of R's NA's. Of course, I have no way of judging the quality of these answers, but I'm curious about whether someone has already looked into this can of worms. url: www.econ.uiuc.edu/~roger Roger Koenker email rkoenker at uiuc.edu Department...

back button support
Hello, I was just wondering what clever ways all the Ajax developers out there have come up with to add back button support to their web apps. I have seen a couple different ways on the net, but neither of them look very complete. Ideally, I would like a solution where I could modify Ajax.Updater to keep track of which pages where loaded into which elements, then create a function like

R and Excel disagreement - Goal Seek versus uniroot
...R2.6.2 I am modeling physical chemistry in collaboration with a friend who has preferred working in Excel. I used uniroot, and find a solution to a two buffer problem in acid-base chemistry which I believe is physiologically sensible. Using "goal seek" in Excel my friend found another plausible root, quite close to zero, and a plot of the function fd below shows that it may be about OK - but Excel fails to find the plausible root indicated by uniroot. fd <- function(H,SID,KA1,KA2,ATOT1,ATOT2){ H^4+H^3*(SID+KA1+KA2)+H^2*(SID*(KA1+KA2)+KA1*KA2-ATOT1*KA1-ATOT2*KA2-kw)+ H*(...
