Stochastic Gradient Ascent for logistic regression
Hi. guys, I am trying to write my own Stochastic Gradient Ascent for logistic regression in R. But it seems that I am having convergence problem. Am I doing anything wrong, or just the data is off? Here is my code in R - lbw <- read.table("http://www.biostat.jhsph.edu/~ririzarr/Teaching/754/lbw.dat" , header=TRUE) attach(lbw) lbw[1:2,] low age lwt race smoke ptl ht ui ftv bwt 1 0 19 182 2 0 0 0 1 0 2523 2 0 33 155 3 0 0 0 0 3 2551 #-----R implementation of logistic regression : gradient descent ---...

Conectividad con Excel
...gt; library(RODBC) Todo bien hasta aqui... Se supone, que en esa librería hay unas funciones que me permiten conectar con Excel, esas funciones son: o -odncConnectExcel2007 o -odncConnectExcel DE tal manera que ahora podría abrir una canal > canalexcel <- odbcConnectExcel2007("lbw.xlsx") Pues esas funciones no están. R me da el error Error: no se pudo encontrar la función "odbcConnectExcel2007" lo mismo con la otra función > canalexcel <- odbcConnectExcel("lbw.xlsx") Y lo curioso es que también me pasa algo similar con la otra posibilidad...

[LLVMdev] generating ELF files on non-ELF platforms with MC
The existence of tools like Wine, LBW and several MachO loaders on Linux is a good indication that at least in most cases, it's possible to run code packaged in some container format on a system favoring another container. In the worst case, the dynamic loader may explicitly choke on some special features, but empirically it seems...

[LLVMdev] generating ELF files on non-ELF platforms with MC
> Yes, what I mean is that I want to generate runnable Windows code, on Windows, but package in ELF as the object file. Note that there's absolutely no problem with this approach - in fact we have a functional prototype already. > The reason for this is that I currently want to employ MC-JIT on both Linux and Windows, without implementing two separate runtime dynamic loaders. I want to

brass and chert / xapian port to Interix
...ends again disabled and the results of 'gmake check' when run on a machine with network access could be posted. All of my work on the Interix port has been done on a hacked and modified SFU Interix 3.5 installation on XP Home. - - - Interix and mmap() semantics are mentioned here: http://lbw.sourceforge.net/broken.html
