Hello, I've seen various threads on people reporting: step factor 0.000488281 reduced below `minFactor' of 0.000976563 While I know how to set the minFactor, what I'd like to have happen is for nls to return to me, the last or closest fitted parameters before it errors out. In other words, so I don't get convergence, I'd still like to acquire the values of the parameters

Hello, I have estimated a simultaneous equation model (similar to Klein's model) in R using the system.fit package. I have an identity equation, along with three other equations. Do you know how to explicitly identify the identity equation in R? I am also trying to forecast the dependent variables in the simultaneous equation model, while incorporating the identity equation in the

Frances, I would not advise Gauss-Seidel for non linear models. Can be quite tricky, slow and diverge. You can write your model as a non linear system of equations and use one of the nonlinear solvers. See the section "Root Finding" in the task view NumericalMathematics suggesting three packages (BB, nleqslv and ktsolve). These package are certainly able to handle medium sized models.

Hi Frances, I have not touched the system.fit package for quite some time, but to solve your problem the following two pointers might be helpful: 1) Recast your model in the revised form, i.e., include your identity directly into your reaction functions, if possible. 2) For solving your model, you can employ the Gau?-Seidel method (see https://en.wikipedia.org/wiki/Gauss%E2%80%93Seidel_method).

Hello, All: What would it take to make ?iconv? portable? I ask, because I want to convert accented characters to vanilla ASCII, thereby converting, e.g., ?Ra?l? to ?Raul?, and Milan Bouchet-Valet suggested on R-help that I use 'iconv(x, ?", "ASCII//TRANSLIT?)?. This worked under Windows but failed on Linux and Mac. It?s part of the ?subNonStandardCharacters? function

Hi, My rsync is stopped working suddenly I got following in verbose and log, mkstemp failed: No such file or directory and rsync error: received SIGUSR1 or SIGINT (code 20) at rsync.c(229) my rsync code : rsync -az -e ssh --delete $HOSTTOBACKUP:$SOURCE $DR_BACKUP_DIR/daily.0 >$tempfile 2>&1 the same code was working last week, what will be the problem, how to proceed to fix?

I would be perfectly fine with Raul & Chandler's proposal, provide that clear documentation is added. The strong distinction between standard library calls and intrinsics is an important point for front end authors. The deliberate ignorance of floating point environment flags is entirely defensible, but needs to be documented clearly. We should also document which rounding mode

Hi, I need to instrument the code in order to generate an event (call a certain function) whenever X instructions have been executed. I'm using MachineFunctionPass to get machine-dependent representation of each LLVM function in the program. However, such pass doesn't allow to modify such functions. Is there any other class so I can modify MachineFunctions? Thanks in advance, Raul. --

Hello! clang defines some AttributeSet, for example: attributes #0 = { nounwind uwtable "less-precise-fpmad"="false" "no-frame-pointer-elim"="true" "no-frame-pointer-elim-non-leaf"="true" "no-infs-fp-math"="false" "no-nans-fp-math"="false" "unsafe-fp-math"="false"

Who was speaking about non-linear models in the first place??? The Klein-Model(s) and pretty much all simultaneous equation models encountered in macro-econometrics are linear and/or can contain linear approximations to non-linear relationships, e.g., production functions of the Cobb-Douglas type.

Dear Raul, Instruction selection and instruction scheduling is, to the best of my knowledge, done at the MachineInstr (MI) IR level. The documentation you've read is on the target independent LLVM IR. You will probably need to read the documentation on LLVM's code generator. The documents on Writing an LLVM Backend, the LLVM Target Independent Code Generator, and Machine IR Format

Klein model is linear but Oseibonsu did not say that explicitly. "Klein

Hello All, I would like your help to learn how to traverse an LLVM DAG and perform some analysis. I know that llc can be used to view a DAG, but I would like to manipulate them. In particular I'm interested in the instruction selection and the scheduling DAGs. I have read the documentation about writing an analysis pass and I know how to traverse a basic block on a LLVM IR assembly file, but

Hi -- I'm working with a number of finance companies in New York City and Chicago which are looking to develop languages and platforms in order to process extremely large datasets. As such, we are looking for people with experience and / or interest in programming language and compiler design -- hence my posting on the LLVM mailing list. Goldman Sachs most famously developed Slang and
