differences between survival models between STATA and R
Dear Community, I have been using two types of survival programs to analyse a data set. The first one is an R function called aftreg. The second one an STATA function called streg. Both of them include the same analyisis with a weibull distribution. Yet, results are very different. Shouldn't the results be the same? Kind regards, J -- View this message in context:

parfm unable to fit models when hazard rate is small
Hello, I would like to use the parfm package: https://cran.r-project.org/web/packages/parfm/parfm.pdfhttps://cran.r-project.org/web/packages/parfm/parfm.pdf in my work. This package fits parametric frailty models to survival data. To ensure I was using it properly, I started by running some small simulations to generate some survival data (without any random effects), and analyse the data using

Great! I thought I had to look at our pipeline at O0 to make sure optimized regalloc was supported (https://bugs.llvm.org/show_bug.cgi?id=33022 <https://bugs.llvm.org/show_bug.cgi?id=33022> in mind).

get means of elements of 5 matrices in a list
I've got a list of 5 matrices that are each 5 x 6. I'd like to end up with a 5 x 6 matrix that contains the mean value of the 5 original matrices. I can do this by brute force, but there must be a better way than making each matrix into a vector and then remaking a matrix thanks very much for any help david freedman ll=list(structure(c(9.7, 17.6, 20.8, 24.1, 33.8, 14.5, 25.7, 29.8,

Highlighting a few bars in a barplot
Hello, I have a bar plot where I am already using colour to distinguish one set of samples from another. I would also like to highlight a few of these bars as ones that should be looked at in detail. I was thinking of using hatching, but I can't work out how or if you can have a background colour and hatching which is different between bars. Any suggestions on how I should do this? Thanks

nested anova not giving expected results
Hello all. This may be a trivially simple question to answer, but I'm a little bit stumped with respect to the calculation of the F statistics in nested anovas in R. If I understand correctly, the F statistic for the among-subgroups but within groups hypothesis is calculated as MS_subgroups/MS_error, while the F statistic for the factor is calculated as MS_factor/MS_subgroups (I'm

[cfe-dev] Who wants faster LLVM/Clang builds?
Hi, I tweaked my scripts to avoid removing includes when it doesn't give any significant benefits, which made the patches significantly smaller. This time the patches should not try to remove includes of header files, which are transitively included from other included header files. The gains mostly remained the same (plus/minus noise), the tables are in the end of the email. I also included

Matrix scalar operation that saves memory?
One possibility might be to use Rcpp. An R matrix is stored in contiguous memory, which can be considered as a vector. Define a C++ function which operates on a vector in place, as in the following: library(Rcpp) cppFunction( 'void subtractConst(NumericVector x, double c) { for ( int i = 0; i < x.size(); ++i) x[i] = x[i] - c; }') Try this function out on a matrix.

The numbers are all separated by comma's and the groups are separated by a semicolon. What I would like to do is read each

compression rate
Hi, I am very fresh man at CODEC part.. I wanna know SPEEX's compression rate.. to say , I tested wav file at 8000 Hz, 8bits to spx file.. I hoped 1/16 compression rate more.. but,, the result was not good for me.. to say example.. I made wav file of 254Kb at 8000Hz , 8bits ...and then encode that file.. the result was that spx file of 33.7Kb is made... so, I though that compression rate
