Determinant and inverse using cholsky parameter
Dear R list members, I have a vector of Cholesky parameterization of a matrix let say A. I would like to compute the determinant and inverse of the original matrix A from the vector of cholesky parameters , would you suggest an R function to do the task. I have tried hard but unable to find anything like that. Please direct me any package or please share R code that can do the task. Thanks and

mle (stat4) crashing due to singular Hessian in covariance matrix calculation
Hi, R developers. when running mle inside a loop I found a nasty behavior. From time to time, my model had a degenerate minimum and the loop just crashed. I tracked it down to "vcov <- if (length(coef)) solve(oout$hessian)" line, being the hessian singular. Note that the minimum reached was good, it just did not make sense to calculate the covariance matrix as the inverse of a

[LLVMdev] VMKIT problem
Hi Nicolas, I'm running it on Kubuntu. Now that you mention it I did have a problem during vmkit setup. After running the ./configure file with all the options I ran the make file it was giving this error: make[3]: *** [/.automount/root/exports/transient/nataraj/Project/vmkit-0.25/lib/Mvm/Runtime/Release/EscapeAnalysis.o] Error 1 " So I went into Makefile.common and modified GNU

[LLVMdev] VMKIT problem
Thanks Nicolas, Gaël I followed your instructions and installed compatible versions of llvm, vmkit and GNU Classpath also I unzipped glibj.zip and pointed GNU Classpath lib variable to the the unzipped files during vmkit configure. That error has vanished. Now when I run jnjvm or vmkit in Release/bin on any file I'm getting a new error : " terminate called without an active exception

[LLVMdev] VMKIT problem
Yes I did, one thing worth mentioning is on running configure for GNU Classpath towards the end this error is displayed and it crashes, I assumed it was okay and went to create the symbolic links and completed the rest of the process with vmkit mentioned in Getting Started as instructed: -I../../../native/jni/native-lib -W -Wall -Wmissing-declarations -Wwrite-strings -Wmissing-prototypes

Have you created the symbolic links to GNU Classpath .so? ie step 2 of http://vmkit.llvm.org/get_started.html?

[LLVMdev] VMKIT problem
Hi Nataraj, You're using incompatible versions of vmkit and GNU Classpath. First, you should use vmkit 0.26 and llvm 2.6 (at least, -- use trunk if there are problems). Second, you should use GNU Classpath 0.97.2. Good luck! Nicolas Nataraj Sundar wrote: > Hi Nicolas, > > I'm running it on Kubuntu. > > Now that you mention it I did have a problem during vmkit setup.

Bootstrapping a covariance matrix
Dear all I am a bit new to R so please keep your swords sheathed! I would simply like to bootstrap a covariance matrix from a multivariate gaussian density. At face value that seemed like a very straightforward problem to solve but I somehow could not get the boot package to work and did not really understand the documentation so I tried to do the bootstrap manually. Hence: x<-rmvnorm(n = 5,

Specifically: profile() is defined as an S3 method in the stats package: function (fitted, ...) UseMethod("profile") <bytecode: 0xa4cd6e8> <environment: namespace:stats> In stats4 it is defined as an S4 method: stats4:::profile standardGeneric for

S3 and S4 clash
Hello: How can I work around the conflict between the S3 and S4 illustrated in the example below? I'm developing a package that requires a function in 'stats4', but when 'stats4' is attached, it breaks my AIC function. I could give my AIC function another name so it no longer uses the generic dispatch, but I wonder if there is another way. Thanks,
