coxreg vs coxph: time-dependent treatment
Dear List, After including cluster() option the coxreg (from eha package) produces results slightly different than that of coxph (from survival) in the following time-dependent treatment effect calculation (example is used just to make the point). Will appreciate any explaination / comment. cheers, Ehsan ############################ require(survival) req...

[RFC] [Windows SEH][-EHa] Support Hardware Exception Handling
As stated in the design paragraph, this design does not intend to model precise CFG at instruction level since it’s complicated and unnecessary. As long as we comply C and C++ rules listed below, we achieve -EHa semantic. There is NO need to precisely model HW exception control flow at instruction-level. Your example about memcpy() is just a bug in current implementation. I will fix it so that it’s volatilized in some manner. We are not in Code Review stage yet. let’s focus on design. There is one seh...

new package: eha
A few days ago I uploaded to CRAN a new package called 'eha', which stands for 'Event History Analysis'. Its main focus is on proportional hazards modeling in survival analysis, and in that respect eha can be regarded as a complement and an extension to the 'survival' package. In fact eha requires survival. Eha contains three func...

[RFC] [Windows SEH][-EHa] Support Hardware Exception Handling
Hi, Eli, Why are you under the impression that threw_exception() will not be called if optimizations are enabled? I don’t know if the -EHa Spec is clearly described in MSFT Webs. At least this proposal has described the rules for both C & C++ code. The very first rule clearly said that “no exception can move in or out of _try region., i.e., no potential faulty instruction can be moved across _try boundary”. As such the derefere...

Thanks, --Ten **** The rules for C code: **** For C-code, one way (MSVC approach) to achieve SEH -EHa semantic is to follow three rules. First, no exception can move in or out of _try region., i.e., no "potential faulty instruction can be moved across _try boundary. Second, the order of exceptions for instructions 'directly' under a _try must be preserved (not applied t...

survreg vs. aftreg (eha) - the relationship between fitted coefficients?
Dear R-users, I need to use the aftreg function in package 'eha' to estimate failure times for left truncated survival data. Apparently, survreg still cannot fit such models. Both functions should be fitting the accelerated failure time (Weibull) model. However, as G?ran Brostr?m points out in the help file for aftreg, the parameterisation is different givi...

Exceptions on Windows & MSVC
...hat is the status regarding exceptions for the windows-msvc target? The corresponding part of the documentation (llvm/decs/ExceptionHandling.rst) hasn't been updated since 2015, was there any progress since? This is most likely known, but there's significant divergence between the behavior of MSVC cl.exe and clang-cl.exe: Consider: void crash() { struct A { ~A() {} } Obj; *(volatile int *)0x11 = 0; } #ifdef SEH #define TRY __try #define CATCH_ALL __except (1) #else #define TRY try #define CATCH_ALL catch (...) #endif int main() { TRY { crash(); } CATCH_AL...

eha aftreg overall p-value
Dear useRs, I am currently fitting an advanced failure time model using G?ran Brostr?m's excellent "eha" library with the "aftreg" command. My question: How do I interpret the "Overall p-value", that is reported at the very bottom of the output? I already figured out it must be a chi-square test, but I am wondering what a p-value < 0.01 means: Does it mean my model fits...

...'m sort of unhappy with the fact that this is theoretically unsound, but maybe the extra effort isn't worthwhile, as long as it doesn't impact any transforms we realistically perform. How much extra effort it would be sort of depends on what conclusion we reach for the "undefined behavior" part of this, which is really the part I'm more concerned about. -Eli From: Ten Tzen <tentzen at microsoft.com> Sent: Wednesday, April 1, 2020 7:55 PM To: Eli Friedman <efriedma at quicinc.com>; llvm-dev <llvm-dev at lists.llvm.org> Cc: aaron.smith at microsoft.com...

Major code is surrounding at SehTryStmt and _Finally in CGexception.cpp that is the place to house Windows SEH specific code anyways. The implementation chose to lever Parser/Semantic phase (SemaStmt.cpp, JumpDiagnostics.cpp, scope.h, etc) to identify the right _Try scope for LU dispatching...
