Panel regression
Hi,
I am trying to run a panel regression where I have a matrix of observations
and a matrix of independant variables - examples would trying to predict
countries's GDP with their data on education, FDI, tax rates, over time.
For the purpose of simplicity, my data would be:
dep = matrix(rnorm(50),ncol=5)
indep1 = matrix(rnorm(50),ncol=5)
indep2 = matrix(rnorm(50),ncol=5)

R Shiny Help - Trouble passing user input columns to emmeans after ANOVA analysis
Hello everybody,
I have experience coding with R, but am brand new to R Shiny. I am trying
to produce an application that will allow users to upload their own
dataset, select columns they want an ANOVA analysis run on, and generate
graphs that will allow users to view their results. However, I am getting

colldiag
Hello,
could anyone explain what am I doing wrong. When I use colldiag function from package perturb I get different Variance Decomposition Proportions matrix in R than in SAS, although the eigenvalues and indexes are the same.
Thanks for your attention.

Calculating mean for a number of columns
Dear all,
I am attempting to perform what should be a relatively simple calculation on a number of data frame columns. I am hoping to find the average on a per-row basis for each of the 50 columns. If on a particular row a 'NA' value is encountered, then this should be ignored and the mean formed on the basis of the other rows.
However, I'm finding that the end result for each row

[LLVMdev] R_ARM_ABS32 disassembly with integrated-as
Getting closer... When emitting symbols, how do I set the symbol's value
to the address of the current instruction? Do I need to emit a label in
the current section and another that uses the former to point to the
latter? If possible, a code sample would be very helpful.
And probably questions for Tim, are these "section-relative" mapping

RC2 artifacts
Hello -- I desperately want to start using Ogg compression on music I
release on the internet, but I am encountering a fair amount of artifacts.
I noticed some in beta4 and was hoping they would disappear with RC1.
However, I've been playing with RC2 and I've still been banging my head into
a number of problems. A majority of the music I make has long drones with a

[LLVMdev] MC disassembler for ARM
That depends on how you define "one ARM instruction." It's not a clear cut thing. For example, is "add r1, r2, r3" the same ARM instruction as "add r1, r2, #4"? What is a distinct instruction and what's a variant encoding of the same instruction is often entirely a matter of convenience.

[LLVMdev] MC disassembler for ARM
Hi Tim,
Thanks a lot for your help! I'm very grateful.
libc.so is a prelinked library, I'll build a non-prelinked one and have
another try.
I'm now at the start of a binary translation project. I want to convert ARM
binary code [*] to llvm ir, which is then translated to binary for our mips
like architecture. That's why I'm looking for a decoder for ARM binary.

[LLVMdev] MC disassembler for ARM
Hi Jim,
Thanks for reply. I'm sorry I didn't make myself clear enough.
The MCInst created by MCDisassembler depends on the instructions defined in
td files. These instructions do not have a one to one mapping to ARM
instructions. There are usually one or more instructions defined in the td
file correspond to one actual ARM instruction.
Thanks,
David

Fwd: Skipping names of temporary symbols increased size of ARM binaries.
CC llvm-dev
---------- Forwarded message ----------
Hello Duncan
The size of ARM binaries created by clang has increased after r236642.
Would you be able to find some time to look at my findings and share your
thoughts about the problem, please?
r236642 prevents emitting of temp label names into object files to save
memory. This is fine, the label names do not appear in the resulting
binaries.

[LLVMdev] R_ARM_ABS32 disassembly with integrated-as
Attached is an example of how to reproduce the issue. It uses a C
file that happens to has a bunch of switch statements which are
encoded as jump tables, giving us data-in-code. Usage:
To build object files with clang via the -integrated-as versus via GCC:
$ export NDK_DIR=<my_ndk_dir>
$ export LLVM_DIR=<my_llvm_bin_dir>
$ make
To test that the generated objects contain the same
