Is there an existing function to compute Cook-Weisberg confidence curves for non-linear model parameters in R?

Hi, I wonder if predict.gam is supposed to work with family=negbin() definition? It seems to me that the values returned by type="response" are far off the observed values. Here is an example output from the negbin examples: > set.seed(3) > n<-400 > dat<-gamSim(1,n=n) > g<-exp(dat$f/5) > dat$y<-rnbinom(g,size=3,mu=g) >

I am trying to explore nlmer by running some nlme examples from Pinheiro & Bates (2000). I do not seem to find information how to specify fixed effects covariates to nlmer models. Specifically, I tried to run the "Carbon Dioxide Uptake" example from p. 368 onwards in the PB200 book. The model without fixed effects covariates runs well but how to tell nlmer to include Type and

I've been testing plotmath. But I'm getting some funny output one one computer. The problem is that characters are 'jumbled' and overstrike when symbols are introduced. Sample code: mu <- 440.0 sigma <- 12.5 myx <- seq( mu - 4*sigma, mu+ 4*sigma, length.out=500) myDensity <- dnorm(myx,mean=mu,sd=sigma) # Here's one way to retrieve the values of mu and sigma and

Hi, I have faced a problem with the merge() function when trying to merge two data frames that have a common index but the second one does not have cases for all indexes in the first one. With usual variables R fills in the missing cases with NA if all=T is requested. But if the variable is a matrix R seems to insert NA only to the first column of the matrix and fill in the rest of the columns by

Hi - Are there any known bugs or other issues that may cause R to crash when trying to use xyplot()? For example, > x<-1:100 > y<-rnorm(100) > library(lattice) Loading required package: grid > xyplot(y~x) causes this: Process R segmentation fault at Wed Apr 3 16:56:42 2002 I am running linux debian unstable on i386.

Hi, I wonder if someone could help. I needed to transfer (copy) a workspace file that had been generated in linux (R 2.11) to windows running the same version of R 2.11 (but of course windows binary). Usually, there is no problem in doing this and all objects work as expected. I am often doing this to be able to produce wmf or emf graphic files that I need. This time I had some spectra that I

Hi, I would appreciate of someone could explain how the residual standard error is computed for rlm models (MASS package). Usually, one would expect to get the residual standard error by > sqrt(sum((y-fitted(fm))^2)/(n-2)) where y is the response, fm a linear model with an intercept and slope for x and n the number of observations. This does not seem to work for rlm models and I am wondering

I believe some low-level tests should actually not be implemented as a separate Analysis but placed into Support. For instance, DeltaTest would use GCD or other tests on a different set of indexes once

Hi, I get the following error message when trying to use the display function on the ARM package: > display(model) Error in .Internal(round(x, digits)) : no internal function "round" Looks like some kind of mismatch between the ARM package and some others? Can I somehow get around it? I have learned to like the display function to print model summaries. Here is my sessionInfo():

This is maybe not directly an R problem but I have used R to try to solve it so I think somebody may be able to help. I have a mixture model with three components and a quadratic Scheffe polynomial p1x1+p2x2+p3x3+p12x1x2+p13x1x3+p23x2x3 fitted to the response. Now I'd like to compute the mixture corresponding the maximum response. Model for Y1 has the parameters p1=124.02 p2=60.973 p3=41.479

I have a fresh installation of R from debian unstable packages. The html index found in /usr/lib/R/doc/html/index.html works in Mozilla and under the link of 'packages' on this page I have a list and corresponding links. However, it appears that not all packages I have installed from available deb files via apt-get, will get their link updated to this package index. Specifically, from

I am new to generalized linear models and studying McCullagh & Nelder (1989). Especially, I have a problem resembling the \"cheese taste\" example (5.3.1. p. 109) of the book. I tried to analyse the cheese example with R but failed to do so because R allowed me to use logit link function only with binary family that supposes 0 <= y <= 1. Do I need to scale the y\'s or

Dear R devels Yesterday I was slightly surprised to notice that R incorrectly detected some of the locale settings. I am not sure whether this is important, but I preferred to drop a message. In the R output below, some entries that should have been "en_GB.UTF-8" are presented as "C". Regards Liviu > sessionInfo() R version 2.9.1 (2009-06-26) x86_64-pc-linux-gnu locale:
