need help EM algorithm to find MLE of coeff in mixed effects model
...but sigma and psi are not close to
the desired values.
Is this due to the limitation of some methods that I used?
Can any one give some help? I am stuck for a week. I can send the code to
you.
First time to raise a question here. Not sure if it is proper to post all
code.
Below is the same as the zip file.

VC2010 (VC10) can't use /Zi option
wine is 1.1.21
I use VC10 beta1 compiler on window, and it's work fine.
The Windows is pure: not install any software.
That mean is: The VC 10 is a portable software.
I can compile main.cpp use:
./cl.exe /EHsc main.cpp
it's OK! the main.exe created!
but if i do:
./cl.exe /EHsc /Zi main.cpp
it's fair.
the error information is:

call an existing IPO pass
...lvm/IR/PassManager.h". I am not quite sure how to invoke these passes in
my own pass. I used "UnifyFunctionExitNodes" in my pass and this one worked
fine.
It will be a great help if anyone can point out how to call the
"CalledValuePropagationPass" in my own pass.
Thanks,

Making LLD PDB generation faster
...t types are duplicates. If
there is a class Foo in a header file, and you include that header file in
100 different translation units, all 100 of them of them will get full type
information for that class in its object file. This is the /Z7 semantics
that clang-cl implements. The alternative is /Zi which uses a type server
(out of process de-duplicater) to do this merging at compile time, which is
what cl uses by default, and which clang-cl doesn't support.

Measure of separation for survival data
.... Although there is no R code for this, the author informs me that it should be easy:
1. Calculate the linear predictor xb from the proportional hazards model or other model of interest.
2. Calculate the ranks r1,...,rn of xb. In case of ties, do not average the ranks.
3. Calculate scaled rankits zi = sqrt(_pi/8) * invnormal((ri - 3/8)/(n +1/4)) where invnormal() is the inverse normal distribution function, and where n is the sample size and _pi = 3.141592654 ...
4. In case of ties in the original xb, substitute average zi's over each of the tied sets.
5. Perform regression (e.g. Cox) on z...

[LLVMdev] codeview debug info in Visual Studio
Hi,
Is there any way to debug the codeview output of llvm from within Visual
Studio?
I want to use the codeview line info debug output of clang/llvm. I tried
with the
x86_64-pc-windows-msvc and i686-pc-windows-msvc triples and linking it
into an
existing project with VC++ from within the IDE and outside with link
/debug.
Neither option lets me debug with Visual Studio as debugger host.
