similar to: Simulating from "matrix variate normal distribution"

Hello everyone I was wondering how would one simulate from a Normal Wishart Distribution in R. A normal inverted Wishart distribution is denoted by NIW (M,C,d,S), where X/(Sigma) ~ N( M,C,(Sigma) ) -> a matrix normal distribution, (Sigma) -> column dispersion matrix (Sigma) ~ IW (d,S) -> inverted Wishart distribution Thanks a lot !

Hello Everyone Both the MCMCpack and the bayesm libraries allow us to make draws from the Inverse Wishart distribution. But I wanted to find out how exactly is the Inverse Wishart distribution parameterized in these libraries. The reason I ask is the following: Now its generally standard to express Inverse Wishart as IW(0.5 * DOF,0.5* Scale). (DOF-> Degree of freedom, Scale -> Scale

Hello Everyone I have a dual-core Intel i3-370M processor and Windows 64 operating system. I have a 3GB RAM and my processor can support a maximum of 8GB RAM. I have virtual memory enabled on my computer. I am running a program in the 64 bit R which implements a MCMC on a large dataset and involves around 80000 iterations. The processor estimates that it will take around 1000 minutes to

Hello Everyone I have a MCMC loop to calculate a time varying hierarchical Bayesian structure. This requires me to use around 5-6 matrix inversions in the loop. I use cholesky and chol2inv for the matrix decomposition. Because of the data I am working with I am required to invert a 167 by 167 matrix twice in one iteration. I need to run the iteration for 10000 times, but I get the error

Hi All, I am trying to achieve ACL set in Public folders, I have public namespace in dovecot.conf like this namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public/ subscriptions = no } and now under public folder I have two subfolders .test and .test1 . I have created dovecote-acl under .test so that it can be seen and subscribe. but I can't see

Hi all, I am using rsync v.3.0.7 (protocol v30) on ubuntu 10.04. My rsync line looks like this, cd /home/shantanu/ rsync -av --files-from=bin/include-to-rsync.dat /home/shantanu/ \ /media/transcend/backup_laptop/shantanu/ include-to-rsync had directories in this format, bank/ dwhelper/ clients/ When I ran the script I noticed that a files in bank/10-11 were not getting synced.

But that's what a jitter buffer will do, eventually - drop a packet. And it's better to drop a silence packet.

Hello All, I have built up my email server with exim + dovecot + clamv/spamassasin. I am using exim as LDA(local delivery agent). I was reading about using dovecot as LDA but I couldn't find why should I use it? Now, I am looking expert advice on "Why should I use dovecot LDA" ? Is there any benefit in terms of functionality or performance ? Any advice/suggestion/feedbacks

Shantanu, let's continue here. You first noticed this on a Dell OptiPlex 755. I think it covers all Dell OptiPlex/Latitude/Precision models that are PCIe based with Intel LoM (LAN on motherboard) utilizing the BIOS PXE OROM, based on the similarity of these systems. The symptoms are that PXELINUX requests pxelinux.cfg/<UUID> by TFTP (but it might not strictly be a TFTP issue) when not

This is a common problem. Sound cards run at different clock speeds (but your difference seems kinda high).

I would like to ''exec'' an installation script ''onlyif'' an installation directory is empty.

Dear all, I would like to generate bi-variate normal data given that the first column of the data is known. for example: I first generate a set of data using the command, x <- rmvnorm(10, c(0, 0), matrix(c(1, 0, 0, 1), 2)) then I would like to sum up the two columns of x: x.sum <- apply(x, 1, sum) now with x.sum I would like to generate another column of data, say y, that makes

Hi, I am a happy user of version 4.06 and have been hoping to upgrade the 5.x series (for the HTTP bits). I have the following problems with the 5.11-pre7 build: 1. TFTP load is horribly slow ... even when the two REAL machines are connected to the same switch. For a typical RHEL installation, the vmlinuz loads ... the initrd.img loads very very slowly and just times out (I waited over 10 mins)
