similar to: Standard error for the area under a smoothed ROC curve?

Dear All, I would like to ask a couple of questions on a LME model. I tested 4 selection lines at 4 food concentrations against a standard competitor stock. I had 3 replicate cages per selection line. In each cage I have 10 vials. I counted the number of wild type flies and competitor stock emerging in each vial. My main question is: is there any difference between selection lines? I did fit

Probably, it's an obvious info, but I have not found anything in R FAQ concerning this feature/bug. The results of ks.test and wilcoxon.test (in the Mann-Whitney version, paired = 'FALSE') don't coincide with the results from the other statistical packages, e.g. Statistica, Medcalc, and (as for MW test) from the numerous online MW tests. E.g. Statistica p-value=0.0435353 Medcalc

Dear All, As some of you in the archive, i am experiencing problems in using RODBC with IODBC on Mac OS X Panther. I am currrently facing two problems. The first one is apparently linked with IODBC (according to returned R error message) although testing the database access from IODBC manager seems to work fine. The second is by far more radical, R purely and simply reports an error ,

Hi, Dear all R users: Does someone know whether R can calculate the Receiver Operating Characteristic (ROC) Curves? I didn't find it from the packages. Thanks a lot. --- Xin

Dear all I am trying to compare the performances of several methods using the AUC0.1 and not the whole AUC. (meaning I wanted to compare to AUC's whose x axis only goes to 0.1 not 1) I came to know about the Mcneil Hanley test from Bernardo Rangel Tura and I referred to the original paper for the calculation of "r" which is an argument of the function cROC. I can only find the

Hi friends, I have questions about printing a pretty big size matrix. As you could see from below, the matrix wasn't showed in R at full size (11X11), but it was cut partly into three smaller matrices (11X4,11X4,11X3). I'm wondering if there is a way to show the whole matrix with dimension 11X11, do you know how to make it? If R really couldn't fit the full big matrix at once, what

I'm compiling syslinux 3.72 as part of a buildroot project and found that the compile fails due to gPXE using printf in a way that throws warnings, while specifying "-Wall -Werror" in the makefile. I'm not sure if this problem is related to the environment I'm compiling in or if it is actually a bug, however the attached patch resolves it for me. -- Regards Nick

Dear R Users, I am hoping you can help me. I have received code from a colleague who uses Matlab. I need to translate it into R. I am wondering if there is a randomization t-test (from non-parametric statistics) function already defined in R. (In Matlab the function is randtest.m.) ************************************************************************ ********** QUESTION: Is anyone

Hello, our sysop's asked me to forward this: Hi everybody, maybe someone can give me a solution to the following problem (get rid of NT unfortunately is no solution). Our net environment contains NT4SP5 and SAMBA servers. Workstations run NT4SP3 and SP5.

Hello R users, I am excited to introduce a new package for R which is now available on CRAN called ?backbone?. The package can be found here: https://cran.r-project.org/web/packages/backbone/index.html The backbone package provides methods for extracting from a weighted graph a binary or signed backbone that retains only the significant edges. The user may input a weighted graph, or a bipartite

Dear list   I have 5 markers that can be used to detect an infection in combination. Could you please advise me how to use functions in ROCR/ other package to produce the ROC curve for a combination of markers?   I have used the following to get ROC statistics for each marker. pred <- prediction(y$marker1, y$infectn) perf <-performance(pred,"tpr","fpr")
