Can anybody, please, explain me how many parameter are estimated using randomLCA? For examples, model "dentistry.lca2random" estimate 1 scale (or variance, b_j) parameter and 2 position parameters (a_cj)? Doesn't it? Do I need at least 4 diagnostic tests for such a model? What happens if I specify options blocksize and byclass? How many diagnostic tests (or rater) I need?

without having to check the vector element by element? Thanks a lot! Jason ===== Jason G.

I am excited to learn that Prof. Tierney is bringing to us compiled R. I would like to learn when it will be available. This information will be useful in scheduling some of my projects. Thanks.

My coauthor made a new R package GeneLogit (100% R code) which installs ok on R 2.3 on Windows. But when I type library(GeneLogit) it gave the error message Error in library(GeneLogit) : 'GeneLogit' is not a valid package -- installed < 2.0.0? It runs on R 1.9.0 just fine. It seems that others have encountered same problem but no solution is found by googling How can I fix this

Hello, everyone! I guess no one is still using R on Sun Sparc these days. But our department has a (pretty new) two-CPU Sun server. We recently compiled R as a 64 bit application and expected a performance boost. But it runs 25-30% slower than the 32 bit version of R. Anyone knows why this is so? Thanks!

I have been using a laptop computer of Pentium III 1.13 Ghz. I heard that AMD's Athlon has excellent floating point capacity. So I bought a Athlon 2200+ laptop yesterday. I expected that new Athlon 2200+ will be twice as fast as the P III 1.13 GB. I ran a R simulation program and the new computer is only 30% faster, in fact slightly slower than a Celeron 1.50 GB laptop. I am very disappointed

Good evening! I have a multi-dimensional minimization problem whose gradient is pretty hard to code. I tried Nelder and Mead method implemented in function optim and it does not work well. I also tried the quasi Newton method in optim using difference as approximate derivative. It does not work well either. I just went through Numerical Recipes book. The book discusses another method without

One of the real advances (in my humble oppinion of course) of 2003 is the Very Fast Multivariate Kernel Density Estimation algorithm by Alex Gray which achieves several order of speed improvement by using Computational Geometry to organize the data. The algorithm is now implemented in C++ with Mathlab interface by Alexander Ihler of MIT: http://ssg.mit.edu/~ihler/code/kde.shtml I wondered if a

I did several simulation sessions and the result turned out to be a surprise. After some investigation, I found that different R sessions of the program used the same seed. Simply, in R210, if I start R and type rnorm(1), I always get the same random number. This is contradictary to what is in the R document Initially, there is no seed; a new one is created from the current time when one

Dear all, is there any possibility to generate a table of homogeneous subsets for multiple comparison tests as in SPSS with R? I am specially interested in Tukey's B test. I have tried to find the answer myself and found an excellent description here: http://www.ppsw.rug.nl/~sda/siv/Posthoc_print.pdf (-> Tab. 2) Together with the information here ...

Dear R-list, I know is going to be weird, but I need to do something about and I know the R-list is big group of good people. I?m moving to Philadelphia in August 2009 (my fianc? is there) and I need to find a job. I know to do so many things, but my skill is in science and research. I would like to know if you know a possible position near Philadelphia, New Jersey or New York. I was working in

The message below, from A, Skwar, appeared last summer. Just in case it got overlooked during vacation time, can anyone comment? I have an example as follows: Every profile contains a foldername "My Recent Documents" which gets changed during a copy to samba disk to "Recent"!! Many similar problems. Also: Special Folder Icons on the screen get changed to generic folder

hi,? I'm working on a research project where we're looking at the changing resonances in femur bones during hip replacement operations. basically, I've got a spreadsheet with one column listing frequencies in 5Hz bands and 3 columns showing the amplitude of that frequency when the bone is loose, medium to tight (referring to the tension of the reamer/chisel creating a cavity for the

Hi Jason, I suppose you installed the Matrix library, and it is working on your computer? If yes, may be det.Matrix() was removed, or renamed in the Matrix library you have (I cannot check this for the latest version, because I am away of the office until August 1st), but I will do that next week. In the meantime, you can replace 'det.Matrix' by 'det.default', and it should run.

Good morning! I recently implemented a KD tree in JAVA for faster kernel density estimation (part of the code follows). It went well. To hook it with R, however, has proved more difficult. My question is: is it possible to implement the algorithm in R? My impression seems to indicate no as the code requires a complete class-object framework that R does not support. But is there an R package or
