Help needed to tackle multicollinearity problem in count data with the help of R
Dear everyone, I'm student of Masters in Statistics (Actuarial) from Central University of Rajasthan, India. I am doing a major project work as a part of the degree. My major project deals with fitting a glm model for the data of car insurance. I'm facing the problem of multicollinearity for this data which is visible by the plotting of data. But I'm not able to test it. In the case

[LLVMdev] GCC compatibility code coverage issue .
Hi Justin , Thank you for the confirmation and we would like to know that ,going forward the clang has the support the gcc gcov format or use the -fprofile-instr-generate -fcoverage-mapping and get ride of gcov format . We are planing to customize the clang code coverage for embedded world ,before we start tweaking the gcov / -fprofile-instr-generate code-base ,we would like to take feedback

MGCV: Use of irls.reg option
Hi, In the help files in the ?mgcv package for the gam.control() function, there is an option irls.reg. The help files describe this option as: For most models this should be 0. The iteratively re-weighted least squares method by which GAMs are fitted can fail to converge in some circumstances. For example, data with many zeroes can cause problems in a model with a log link, because a mean of

R help - bootstrap with survival analysis
Hi, I'm not sure if this is the proper way to ask questions, sorry if not. But here's my problem: I'm trying to do a bootstrap estimate of the mean for some survival data. Is there a way to specifically call upon the rmean value, in order to store it in an object? I've used print(...,print.rmean=T) to print the summary of survfit, but I'm not sure how to access only rmean

[LLVMdev] SchedMachineModel clarifications
I made a quick cross check with information in the SWOG (Software Optimization Guide). The port assignments look consistent. A few of the latency values are slightly different from the SWOG, e.g. WriteFRcp --> 6, WriteFSqrt --> 29 and WriteCvt* --> 4 seem to be suggested instead. Others are in better position to describe how to use llvm performance framework. --mev, Mike Vermeulen

[LLVMdev] Unwanted push/pop on Cortex-M.
Umesh, Makes some sort of sense to me, OTOH: If instead of choosing r11 as a "dummy" to align the stack we had chosen some other register in the range r0-r7 then we could have emitted the PUSH encoding T1 (2 bytes opcode) as opposed to the encoding T2 (which is a 4 bytes opcode).

interpreting glmer results
Hi all, I am trying to run a glm with mixed effects. My response variable is number of seedlings emerging; my fixed effects are the tree species and distance from the tree (in two classes - near and far).; my random effect is the individual tree itself (here called Plot). The command I've used is: mod <- glmer(number ~ Species + distance + offset(area) + (1|Plot), family = poisson)

[cfe-dev] How to debug if LTO generate wrong code?
(And I doubt the GNU linker supports LTO with LLVM). [Steven]: I’ve pushed GNU Binutils ld to support LLVM gold plugin, see detail in this bug https://sourceware.org/bugzilla/show_bug.cgi?id=20070. The new GNU ld linker works well with LLVM/Clang LTO when build IA32 code in my side. And from the ld owner input in the bug comments, the current X64 LLVM LTO issue is in llvm LTO plugin. The fact

Debug Info is not generated for extern variables .
I think emitting "testExt" as an external declaration (what gcc does) doesn't do much for the debugger; being a declaration, it has no location, and so you can't do things like examine its value, unless you find the symbol in the defining CU first. I don't see a real "compatibility with gcc" argument here. Is there some behavior of some consumer that is affected

[cfe-dev] How to debug if LTO generate wrong code?
Hi Mehdi, GCC LTO seems support large code model in my side as below, if the code model is linker specific, does the GCC LTO use a special linker which is different from the one in GNU Binutils? I'm a bit surprised if both OS X ld64 and gold plugin do not support large code model in LTO. Since modern system widely use the 64bit, the code need to run in high address (larger than 2 GB) is a

[cfe-dev] How to debug if LTO generate wrong code?
Hi Mehdi, After deeper debug, I found my firmware LTO wrong code issue is related to X64 code model (-mcmodel=large) is always overridden as small (-mcmodel=small) if LTO build. And I don't know how to correctly specific the large code model for my X64 firmware LTO build. Appreciate if you could let me know it. You know, parts of my Uefi firmware (BIOS) have to been loaded to run in high
