Installing SJava - problem
Hi there. I am trying to install SJava on my windows xp machine. I downloaded the windows source file SJava_0.69-0.tar.gz from the web site http://www.omegahat.org/RSJava/ I have folloed the XP command line instructions as directed in the table underneath the download link: cd $RHOME/src/library unzip SJava_0.69-0.zip cd SJava ./configure.win $RHOME cd $RHOME/src/gnuwin32 make pkg-SJava I

Penalized likelihood-ratio chi-squared statistic: L.R. model for Goodness of fit?
Dear R list, From the lrm() binary logistic model we derived the G2 value or the likelihood-ratio chi-squared statistic given as L.R. model, in the output of the lrm(). How can this value be penalized for non-linearity (we used splines in the lrm function)? lrm.iRVI <- lrm(arson ~ rcs(iRVI,5), penalty=list(simple=10,nonlinear=100,nonlinear.interaction=4)) This didn’t work

firth's penalized likelihood bias reduction approach
hi all, I have a binary data set and am now confronted with a "separation" issue. I have two predictors, mood (neutral and sad) and game type (fair and non-fair). By "separation", I mean that in the non-fair game, whereas 20% (4/20) of sad-mood participants presented a positive response (coded as 1) in the non-fair game, none of neutral-mood participants did so (0/20). Thus,

penalized maximum likelihood estimation and logistf
Hi, I got two questions and would really appreciate any help from here. First, is the penalized maximum likelihood estimation(Firth Type Estimation) only fit for binary response (0,1 or TRUE, FALSE)? Can it be applied to multinomial logistic regression? If yes, what's the formula for LL and U(beta_i)? Can someone point me to the right reference? Second, when I used *logistf *on a dataset with

survreg penalized likelihood?
What objective function is maximized by survreg with the default Weibull model? I'm getting finite parameters in a case that has the likelihood maximzed at Infinite, so it can't be a simple maximum likelihood. Consider the following: ############################# > set.seed(3) > Stress <- rep(1:3, each=3) > ch.life <- exp(9-3*Stress) > simLife <- rexp(9,

How to get the penalized log likelihood from smooth.spline()?
I use smooth.spline(x, y) in package modreg and I would like to get value of penalized log likelihood and preferable also its two parts. To make clear what I am asking for (and make sure that I am asking for the right thing) I clarify my problem trying to use the same notation as in help(smooth.spline): I want to find the natural cubic spline f(x) such that L(f) = \sum_{k=1}{n} w[k](y[k] -

VGAM package released on CRAN
Dear useRs, upon request, the VGAM package (currently version 0.7-1) has been officially released on CRAN (the package has been at my website http://www.stat.auckland.ac.nz/~yee/VGAM for a number of years now). VGAM implements a general framework for several classes of regression models using iteratively reweighted least squares (IRLS). The key ideas are Fisher scoring, generalized linear and

breslow estimator for cumulative hazard function
Dear R-users, I am checking the proportional hazard assumption of a cox model for a given covariate, let say Z1, after adjusting for other relavent covariates in the model. To this end, I fitted cox model stratified on the discrete values of Z1 and try to get beslow estimator for the baseline cumulative hazard function (H(t)) in each stratum. As far as i know, if the proportionality assumption

Question about Installing SJava package
Dear all, I have an error message installing SJava package. So I searched web site(google) and R-mailing list to find a similar error message. But I couldn't find it.

SJava 0.65 and R 2.0.0 (slightly long)
Hi, I had some Java code that worked with SJava 0.65 under R 1.8.*. I'm trying to get it to work with R 2.0.0. My JVM is Sun 1.5.0 (running on Fedora Core 2) I downloaded and installed SJava 0.65 in my personal directory using R CMD INSTALL SJava-0.65.tar.gz -l ~/src/Rlibrary and before starting R I sourced RJava.bsh. However after loading the SJava library if do javaConfig() I get

Sjava question on MacOS 10.3
I am running R-1.81, apple's JVM installed with OS 10.3.2, and installed Sjava-0.65.X (a patched version of Sjava for MacOS from Simon Urbanek, which I know is inherently dangerous, but...). This version installed fine and some aspects seem to work as expected. However, this is one of the examples and causes R to hang. Any insights? What other information should I provide to make it easier
