similar to: classification table in logistic regression

Prof. Harrell, My name is Armida Carbajal, I'm a graduate student intern at Sandia National Laboratories (SNL) and am conducting some research for my thesis project at the University of New Mexico in Statistics for SNL. My project entails a logistic regression and I wanted to create a classification table like the one found in SAS using the function CTABLE. I was running out of ideas on

Hello, I use Gentoo and I can't get R 2.0.1 to compile. I used the portage system, Gentoo's source package sytem, and after it uncompresses the source to R, it says that I don't have a fortran compiler. It told me to use f77 flag and re-emerge gcc, which I did with the f77 and fortran flags, but it still won't compile. Does anyone have any ideas? I suspect that gcc has changed

Hi, pretty new with R and LaTeX here... I'm trying to use the latex() function from the Hmisc table with Sweave. When I try: pdflatex myfile.tex I get an error that reads: ! Undefined control sequence. l.22 \ctable It seems like this is an optional package for Tex that I haven't installed? My googling skills have neglected to locate instructions for how to install ctable on a Mac,

Dear all, With the latest update of Hmisc I no longer have any problems with latex. However using the ctable option produces latex code that at least on both the miktex distribution at work and mactex distribution at home refuses to run due to an extra blank line inserted between the multicolumn lines in the latex code... It runs fine if the line is deleted or if the ctable option is left out.

Dear Colleagues, I would like to do classification using logistic regression. Which R package can I use? Also is there any package for feature selection for logistic regression based method? Thanks a lot in advance. Happy holidays. Regards, Raj [[alternative HTML version deleted]]

Dear Ioannis Thank you very much for pointing me to meta-analysis. Although it may not solve my problem with the normalization, it gives me some other options to display the different correlation coefficients. One possibility is the use of Funnel plots, which are even available in library(rmeta). Another possibility is the use of forest-plots, as implemented in rmeta as metaplot. Sorrowly,

Dear R People: Please excuse the off topic question. What are the dimensions of A-4 Paper, please? Actually, the question should read, "how do I set up a LaTex file to fix A-4 paper, please?" Thanks much! Sincerely, Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: hodgess at gator.uhd.edu

Dear friends, I'm doing a simulation on logistic regression model, but the programs can't work well,please help me to correct it and give some suggestions. My programs: data<-matrix(rnorm(400),ncol=8) #sample size is 50 data<-data.frame(data) names(data)<-c(paste("x",1:8,sep="")) #8 independent variables,x1-x8; #logistic regression model is

Dear useRs, When I'm using Hmisc's latex() function with ctable=TRUE on a summary.formula with method="reverse" object and saving in a .tex file, the latter contains an unwanted empty line which makes compilation fail. Here is a brief example : library(Hmisc) test <- data.frame(a=sample(1:30,10),b=sample(c("good","bad","ugly"),10,replace=T))

Hi all, I'm looking for a program that will take the predicted probabilities from a logistic regression using glm{stats}, dichotomize them according to a threshold that I can control, and then use them to form sensitivity, specificity, false pos and false neg rates. Thanks in advance. David -- ======================================================================= David Kaplan, Ph.D.

Dear R users, I would like to fit cross classified or multiple membership logistic models or a 3 level hierarchical logistic model using the Umacs package. Can anyone advise me on how to proceed or better point me to examples of how its done.

Hi Dimitry, this definitely worked. I am passed by the linking errors regarding libc++ or similar. My build stopped now at 95% while linking a clang extra, I am not pretty sure which because i do not have my laptop, possible the clang-rename, if such exists. No undefined references here, however, my hdd's free space run out, so this might be the cause. I have to move or expand now, alas!! The

Dear Mr Peter Dalgaard and Mr Dieter Menne, I sincerely thank you for helping me out with my problem. The thing is taht I already have calculated SENS = Gg / (Gg + Bg) = 89.97% and SPEC = Bb / (Bb + Gb) = 74.38%. Now I have values of SENS and SPEC, which are absolute in nature. My question was how do I interpret these absolue values. How does these values help me to find out wheher my model is

Hello, I am using logistic discriminant analysis to check whether a known classification Yobs can be predicted by few continuous variables X. What I do is to predict class probabilities with multinom() in nnet(), obtaining a predicted classification Ypred and then compute the percentage P(obs) of objects classified the same in Yobs and Ypred. My problem now is to figure out whether P(obs) is

Dear R users: When I create a table without Major Column headings, my *regular* column headings appear correct in the typeset latex file. The major row heading and row groups are as they should. w <- latex(mytab,title="",file="tab/my.tex",ctable=TRUE,caption="Descriptive statistics by

Hi Ioannis, Just delete the projects/libcxx directory, then rebuild from scratch. You should only need to checkout llvm (in the top level directory) and cfe (into the tools/clang subdirectory). -Dimitry > On 29 Mar 2016, at 00:08, Ioannis Koukoulis <i.g.koukoulis at gmail.com> wrote: > > Hi Dimitry, > > I do not particularly need to build libc++ from the package.
