Dr. Frank E. Harrell, Jr., Professor and Chair of the Department of Biostatistics at Vanderbilt University is giving a one-day workshop on Regression Modeling Strategies on Friday, April 29, 2005. Analyses of the example datasets use R/S-Plus and make extensive use of the Hmisc library written by Professor Harrell.The workshop is sponsored by the Southern California Chapter of the American

The workshop organizing committee of the Southern California Chapter of the American Statistical Association announces the 28th Annual Workshop in Applied Statistics. Professor Colin Cameron from the department of Economics at UC Davis will give a one-day workshop titled "Advances in Count Data Regression." The event will take place on Saturday, March 28, 2009 at UCLA. Details on

Hello, The call for papers for SCALE 4x, the 2006 Southern California Linux Expo, is now open. This event will be our fourth annual show. It will be held on Feb 11-12, 2006 at the Los Angeles Airport Westin. We are expecting 1,300+ in attendance this year. We are non-profit, community run Linux, open-source and free software conference. If you are working on something you believe the

Hello R-help! I am a systems administrator for the University of Southern California. I take care of it's general-purpose research cluster, and have recently been asked to provide access to a parallelized R platform. I do not have any previous experience using R, and have only ever had to do anything more then 'yum -y install R'. We have a myrinet MPI network, and use mpich1 as our

Hello, I am trying to learn how to do PCA. I found a tutorial online, but what I'm seeing in my installation does not match what is in the tutorial. Specifically, if I select Statistics:Dimensional Analysis: Principal-components analysis, the dialog I am presented with does not include an option to create an ordination plot. My question is why not? Is this a problem with my data set,

Dear R users, Two questions: 1) Is there a way to simplify the mtext() line below ? beta=c(1,-1) m=5 plot(1) mtext( bquote(paste( beta == .(paste( "(", paste(beta, collapse=", "), ")" )) )), outer=TRUE,line=-3) 2) How do I get the embedded carriage return "\n" below to work, i.e for the text that follows it to appear on the next line? beta=c(1,-1) m=5

Could anyone help with a linear mixed model fitting problem ? The model is : Y= Xp + Zu + e where X, Z are known design matrix, p is fixed effect factor, u is random effect, u~ (0, G) , e~(0,R) The main problem is , I want to fix the covariance matrix G to be a constant times a known covariance matrix A, G = c*A (c is positive constant, A is a predefined matrix with values manually set by

Dear R users, Consider the following example function: f = function(a,b) { g = function(x) a*x + b h = function(x) g(x)^2 + x^2 opt = optimize(h,lower = -1, upper = 1) x.min = opt$minimum h.xmin = opt$objective g.xmin = g(x.min) return(c(x.min, h.xmin, g.xmin)) } In my real problem the function that plays the role of "g" is costly to compute. Now, to

Hi: I really liked the music on your 32kbps stream. That is what I listened to. It is very high quality low bandwidth. You must have a recording studio as well as the station. The website for the Linux Public Broadcasting Network is www.lpbn.org I'll create a mailing list for radio on LPBN later tonight so our emails don't disrupte the kind folks at icecast. Just a note, on Sunday I

I want to create a simple plot containing three levelplots with one colorbar. I used the "Three levelplots" code below, but the third levelplot is drawn smaller than the first two. However, if I try the "Two levelplots" code below it works well. Can anybody tell me how could I draw three levelplots (of the same size) with one colorbar. Thanks in advance, Joaquin ### Three

All- I am interested in estimating a parameter that is the starting value for an ODE model. That is, in the typical combined fitting procedure using nls and lsoda (alternatively rk4), I first defined the ODE model: minmod <- function(t, y, parms) { G <- y[1] X <- y[2] with(as.list(parms),{ I_t <- approx(time, I.input, t)$y dG <- -1*(p1 + X)*G +p1*G_b dX <-

Greetings, I would like to formerly invite the CentOS community to participate at the Southern California Linux Expo. The show will be taking place February 20th - 22nd, 2009 at the Westin LAX in Los Angeles, CA. I am including both a link to our "Call For dotORG Exhibitors" as well as our "Call for Papers" if anyone from the CentOS community is interested in submitting a

Greetings, I would like to formerly invite Vorbis and the other Xiph projects to attend the 7th Annual Southern California Linux Expo. The show will be held February 20th-22nd, 2009 once again at the Westin LAX in Los Angeles, CA. Because the Xiph projects are open source projects, SCALE will provide a complementary booth on our show floor including all the usual amenities such a 6' table

In the robust library of S+, it is possible to compute Rocke's constrained M-estimator of scatter and location. Can't find anything within R that does the same thing. Can someone tell me whether any package exists for computing it? Thanks. Rand Wilcox Professor Dept of Psychology University of Southern California Los Angeles, CA 90089-1061 FAX: 213-746-9082

Hello- I have a client in Orange County California who will soon need some consulting assistance with their new asterisk system. I've been asked to help them find someone. Skills needed would be, in order of importance: Basic experience configuring and using asterisk, coding experience in Perl, experience with MySQL or equiv., and a knowledge of telephony terminology and

Greetings, A couple of questions: 1. I am using wireframe. It prints 3d plots nicely on screen, but when I use a postscript device the z-axis label merges with the z-axis. Is there any option to control their separation? 2. Again, using wireframe, I rotate the whole plot using the screen parameter. However, the x- and y-axis labels (xlab and ylab) remain horizontal. How could I rotate them?

Hello, I'm doing bayesian network analyses with the deal package. I am at a loss for how to interpret output from the analysis (i.e. what is a good score, what is a bad score, which stats tell me what about the network edges/nodes). Here is an example node with its posterior scores for all parent nodes. ------------------------------------------------------------ Conditional Posterior:
