Dear list, I am needing to extract the estimate of overdispersion (deviance / residual degrees of freedom or c-hat) from multiple model objects - so they can then be used to compare the extent of overdispersion among alternative models as well as calculate qausi-AIC values. I have been unable to do this, despite consulting a number of manuals and searching the R-help. I am imaging that in

Dear list, I am having some problems with extracting Variance Components from a random-effects model: I am running a simple random-effects model using lme: model<-lme(y~1,random=~1|groupA/groupB) which returns the output for the StdDev of the Random effects, and model AIC etc as expected. Until yesterday I was using R v. 2.0, and had no problem in calling the variance components of the

Dear helpers, I wrote a code which estimates a multi-equation model with generalized least squares (GLS). I can use GLS because I know the covariance matrix of the residuals a priori. However, it is a bit slow and I wonder if anybody would be able to point out a way to make it faster (it is part of a bigger code and needs to run several times). Any suggestion would be greatly appreciated. Carlo

We have just upgraded from Samba 1.9.18p7 to 2.0.6. We are now encountering this problem with 2.0.6 which was discussed back in 1998. We never had the problem with 1.9.18p7. We haven't changed the smb.conf as we are just using Samba in basic fileserver mode. Is there a change we need to make to get rid of this message and restriction occuring? Andrew 1998 Discusion: >I have a

This is a serious problem which can affect users of Samba in a Windows 2000 domain in which a Group Policy is applied to user accounts to redirect the "My Documents" or other folders to a Samba share. The contents of the users "My Documents" can become deleted. Problem description: 1. Background : We are using Samba servers to serve user files in a Windows 2000 domain of

Please could a Samba developer or user answer these questions. Background: We use Samba for serving files, and it has worked extremely well in this simple mode for 20,000 plus users in this university for the previous 3/4 years. Thanks to all those involved for this excellent software. We are soon to implement Windows 2K and Active Directory as the university's primary authentication

Hi there, I have recently updated to ver 2.10 (windows - I'm running xp) and find I am having problems with plot arguments, for e.g. Using the errbar function the error bars are now in black despite col="red", the central point is in red though. Axis labels are drawn but not the 'main' title. No errors are reported. Using the plot function directly I was only able to

R ran find on our Sun until it was stolen. I have now set up R on one of our Dec Alphas OSF1 V4.0 386. R-0.49 configures builds and runs fine except that the glm command crashes R. R-0.60.1 configures builds and runs until a cis entered. I think the problem is the floating point conventions but before I get in over my head a question Has anyone used glm successfully on Alphas OSF1 V4.0 386?

I am new to R so may well have missed the point somewhere. I would like to use an exponential error in my generalized linear model. It seems natural to restrict the Gamma family to do this ( and as one might in GLIM) by specifying the scale. This does not seem possible in R . Have I missed something? Sorry to raise such a trivial point but I am keen to specify the scale G.Janacek

I hope this is the right place for my question, my apologise if it is not. I am a long time Mac/UNIX user and my local machine is a Mac. At present I run an orphan version of R which a worried out of (*****). On reflection I guess I'd better not say, but it changed my life. It is howerver a little out of date ( say 0.6ish) So the obvious question, do I move to MacLinux or is there likely

I am trying to give my students acces to R. rsept (the windows95 version ?) will not run on our setup which is PC's connected to a server. rapril (the 3.11?) version will run but the graphics vanish once the graphics window is activated. Any suggstions? I did try mounting it on a DEC Alpha but getting a version to run glm is beyond me. I would appreciate any suggestions Jan G.Janacek

We are experiencing problems with Adobe Photoshop and Samba, all versions up to 2.0.6. We run Samba off Compaq Alphaservers (ie 64 bit). Symptoms: 1) On doing a "Save As" in Photoshop, we intermittently get: "Could not save as F:\<filename> because the file is already in use or was left open". A zero length file is left on the Samba share. 2) Problem only

Is it possible to get R to output the value of an expression, that is being calculated within a function? I've attached a very simple example but for more complicated ones would like to be able to debug by seeing what the value of specific expressions are each time it cycles through a loop that executes the expression. I'm relatively new to this so there may be much simpler more elegant

Dear helpers, I am using R version 2.5.1 to estimate a multinomial logit model using my own maximum likelihood function (I work with share data and the default function of R cannot deal with that). However, the computer (I have an Athlon XP 3200+ with 512 GB ram) takes quite a while to estimate the model. With 3 categories, 5 explanatory variables and roughly 5000 observations it takes 2-3 min.

Dear list I try to run a bootstrap with lmer. I often, but not always, get the error message: Error in objective(.par, ...) : Leading minor of order 6 in downdated X'X is not positive definite (with the number (here 6) varying) In R-archives I came across some threads that treated this problem, nevertheless they refer to lmer when using it with family = "binomial", so the

I am running some simulations which involve fitting a glm with Binomial error ( in fact Bernoulli) and logistic link. Running R 0.63 I have no problems. However I need more speed so migrated to our UNIX boxes which run Version 0.90.1 (December 15, 1999) Here I get an error Error in (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y, : y must be univariate unless binomial

Dear All, After playing with lmer for couple of days, I have to say that I am amazed! I've been using quite some multilevel/mixed modeling packages, lme4 is a strong candidate for the overall winner, especially for multilevel generzlized linear models. Now go back to my two-level poisson model with cross-classified model. I've been testing various different model specificatios for the
