I have the same problem of a previous request HOW to use the survivalROC (or another library in R) to get optimal cut-off values? I want to use the time-dependent survivalROC package.according to the,reference material,it only gives a partial set of ordered cut-off values .eg. -------------------------------------------------------------------------------- data(mayo) str(mayo) attach(mayo)

I have some question about metafor package.

Dear all I generated predicted risk of death for each subject in the study by means of Cox proportional hazards model at 8 year of follow-up, a time point at which follow-up was more than 90% complete. It is possible to extrapolate to 10-year the predicted risk of each subjet by assuming an exponential distribution? Any help would be greatly appreciated. Thanks for your consideration.

Dear all, I am interested to evaluate reclassification using net reclassification improvement and Integrated Discrimination Index IDI after survival analysis (Cox proportional hazards using stcox). I search a R package or a R code that specifically addresses the categorical NRI for time-to-event data in the presence of censored observation and, if possible, at different follow-up time points. I

Dear all, I'm interested in fitting survival trees with competing risk analysis. The tree should show the cumulative incidence function for each terminal node . I read several paper illustrating this possibility, but to the best of my knowledge no R code are reported. There is any R package for this fit? Thank you very much in advance. Mario Petretta

Hi, I have tried to install the R package Rcplex on windows xp without success. I have only cplex_studio124.win-x86-32 version. I have modified the makevars.win file as indicated in the installation guide ( http://cran.r-project.org/web/packages/Rcplex/INSTALL ), then I zipped the whole folder to order an installation from a zipped file (utils :menuInstallLocal()) The message I had is file

Hi all, I am just starting with R and I have come across a problem which I guess it is easy to solve. I am reading a table with read.table function. This table contains chars which seem to be problematic when reading them such as "'" and "#", if I remove these characters fromt the table by hand the problem disappears. Otherwise, the whole table is not read, since reading

Dear All, I just apt-get source r-base-core and noticed that file "rules" under ./r-base-3.2.4-revised/debian contains (lines 277 to 279) --with-system-bzlib \ --with-system-pcre \ --with-system-zlib \ I wonder if these are still necessary and, in fact, when building R alpha (specifically, R-alpha_2016-03-21_r70361.tar.gz) I get a warning saying that those options are not

Sirs, I have recently been interested in your Maxstat. I have computed with my own programme the ranks (by using the Kaplan-Meier method and the log-rank test) with the formula (Observed-Expected)/(SQR Var). The results are similar but not exact to the M value obtained with the Maxstat. I would like to know whether you are using some correction or adjustment in computing the different ranks. Thank
