...analysis and methods development. Familiarity with neurophysiology is not required. Familiarity with R and with some of the methodologies used: clustering, classification, MCMC, counting processes, is a big plus. For more information please visit: http://www.biomedicale.univ-paris5.fr/physcerv/C_Pouzat/PostDoc1.html The second position starting in September to develop methods for the analysis of Calcium imaging data from neuronal preparation is also available. Familiarity with neurophysiology is not required. Familiarity with R and with maximum likelihood estimation of models based on non-li...

Dear list users, I need to learn about MCMC methods, and since there are several packages in R that deal with this subject, I want to use them. I want to buy a book (or more than one, if necessary) that satisfies the following requirements: - it teaches well MCMC methods; - it is easy to implement numerically the ideas of the book, and notation and concepts are similar to the corresponding R

Hello, I am looking for documentation (PDF ?) about doing clustering with the EM Algorithm on R... I'm sorry for this question which may be trivial... Thanks... Dominique

Hi, list, Sorry if I am bothering you. I am interested in using xgrid with R for distributed computing. I am using MacOS X and my R 2.1. 1 is already installed and running. The client computers are all of the same type and the same version of R has been installed on them. We have also set up xgrid on my system and client computers as well. I am wondering if any one can give me some clues

Hello, I've got to compute a minimization equation under an equality constraint (Min g(x1,x2,x3) with x1+x2=const). The Constroptim function does not authorize an equality condition but only inequality conditions. Which function can I use instead? Thank you very much for your help.

Hi all, I'm trying to estimate a nested model (purchase decision, cloglog formula, & quantity bought given a purchase, truncated Poisson). Some of the parameters are mixed (6) and 4 are fixed for all the respondent. The simulated ML (500 simulations) method forwards highly correlated estimates. After some research, Hybrid Monte Carlo seems to be a good alternative to estimate the model. I

Full_Name: Reinhold Bader Version: 2.1.0 OS: SLES 9 Submission from: (NULL) (129.187.48.1) I tried to build R using the Intel compilers (icc, ifort) and the Math Kernel Libraries for BLAS/LAPACK Optimizations used were -O3, and the FPICFLAGS="-fpic" was exported. The build failed with the following error message: ... dumping R code in package 'methods' Saving namespace image

I have some time stamped events that are supposed to be unrelated. I have plotted them and that assumption does not appear to be valid. http://metrak.com/tmp/sevents.png is a plot showing three sets of events over time. For the purpose of this exercise, the Y value is irrelevant. The series are not sampled at the same time and are not equispaced (just events in a log file). The plot is
