I am trying to optimize custom likelyhood with nlminb() Arguments h and f are meant to be fixed. example.R: compute.hyper.log.likelyhood <- function(a, h, f) { a1 <- a[1] a2 <- a[2] l <- 0.0 for (j in 1:length(f)) { l <- l + lbeta(a1 + f[j], a2 + h - f[j]) - lbeta(a1, a2) } return(l) } compute.optimal.hyper.params <- function(start, limits, h_, f_) { result

Dear community, I am currently trying to fit an ordinal logistic regression model with the polr function. I often get the same error message : "attempt to find suitable starting values failed", for example with : require(MASS) data(iris) polr(Species~Sepal.Length+Sepal.Width+Petal.Length+Petal.Width,iris) (I know the response variable Species should be nominal but I do as levels

Dear friends i am trying to fit an Ornstein-Uhlenbeck process by MAXIMUM LIKELYHOOD method. i found these formulas on http://www.sitmo.com/article/calibrating-the-ornstein-uhlenbeck-model/ this is the mean-reverting process http://r.789695.n4.nabble.com/file/n4637271/process.txt process.txt and this is the script that i am using....... ouFit.ML=function(spread) { n=length(spread)

Hi ! Not very blocking because the smp module loads perfectly. # yum --exclude=kmod-drbd*\plus\* install kmod-drbd Setting up Install Process Setting up repositories Reading repository metadata in from local files Excluding Packages in global exclude list Finished Reducing CentOS-4 - Plus to included packages only Finished Parsing package install arguments Resolving Dependencies -->

What is the likelyhood that major inexpensive webhosts like godaddy, bluehost, etc. will upgrade to RoR 1.1? Is this going to be like PHP 5 where it has to percolate for a year or more before it becomes widly available? Your thoughts? Along the same lines... is it possible to adopt some of the new improved Ajax / javascript capabilities without actually upgrading the ruby installation?

Hi everyone, I´m using Citrix XenServer with DRBD. But something went really wrong, so I need a fresh Install.My only question is, how can I mount the DRBD partition? It is /dev/drbd1 , but if I try to mount it, I need to provide the filesystem type. Does anyone know what I have to do? I only need to copy some data from it, it doesn’t matter if it will be destroyed. I tried GFS as filesystem

Hello all, has someone worked with DRBD (http://www.drbd.org) for HA of mail storage? if so, does it have stability issues? comments and experiences are thanked :) Thanks, Rodolfo.

Hi, I've upgrade the kernel to the latest version (C5) and after the update the drbd is not being loaded at reboot time. My previous running kernel was 2.6.18-164.el5. I've checked the /lib/modules/ and /lib/modules/2.6.18-164.10.1.el5/weak-updates/drbd82/drbd.ko -> /lib/modules/2.6.18-164.el5/extra/drbd82/drbd.ko And /lib/modules/2.6.18-164.el5/extra/drbd82/drbd.ko exists 2004

Hello, This morning I noticed the following output from "yum update": Installing: drbd82 x86_64 8.2.5-1.el5.centos extras 209 k replacing drbd.x86_64 8.0.11-1.el5.centos As far as I'm aware DRBD works fine for me. Is there a way I can find out about the new release and weather I should upgrade? I can't figure out the CentOS issue tracking system

Hi everyone, I am wondering what the likelyhood would be to get a "delete machine script" implemented in the samba core that would delete a machine upon successful un-join of a samba domain. Alternatively, why is this not a good idea? tom.

I'm running CentOS 4.4 and drbd 0.7 with ext3 filesystems on the drbd device. I'm very interested in moving to drbd 0.8 and pulling my all of my drbd devices into one lvm for greater flexibility in filesystems. I've seen some notes on doing this but wonder if anyone on this list has a cookbook for doing this. Also noted that on the drbd site the only packages they have are set

Will there be a matching DRBD kernel module package for the latest kernel that is in the updates repository? The kernel version in the updates is: kernel-smp-2.6.9-34.0.1.EL.i686.rpm but I don't see a matching DRBD module in updates. Thanks, Steve

Hi, I am trying to use drbd in my centos 5.4 but I keep getting errors. When I try modprobe -v drbd I receive insmod /lib/modules/2.6.18-164.el5PAE/extra/drbd/drbd.ko FATAL: Error inserting drbd (/lib/modules/2.6.18-164.el5PAE/extra/drbd/drbd.ko): Invalid module format. The current (running) kernel is 2.6.18-164.el5PAE kmod-drbd-8.0.16-5.el5_3 drbd-8.0.16-5.el5.centos Any tips?

Hej folks, I''m messing around with DRBD once again but with a new Xen 4.1.2 installation using the XL toolstack instead of the xend daemon. However, after getting my DRBD installed and a device operational, trying to create a domU using the drbd block device doesn''t want to work: xl create -c test.cfg Parsing config file test.cfg Unknown disk type: drbd My config has: disk

Hi, I have a server with Centos 5 + DRBD installed and is working fine, but when i run yum for udpate system show this error: Transaction Check Error: file /etc/drbd.conf conflicts between attempted installs of drbd-8.0.12-1.el5.centos and drbd82-8.2.6-1.el5.centos file /etc/rc.d/init.d/drbd conflicts between attempted installs of drbd-8.0.12-1.el5.centos and drbd82-8.2.6-1.el5.centos file

Hiya, I'm new to Centos but learning rapidly but I have been using FreeBSD. I'm trying to setup a HA NFS server using 2 machines. Both machines are running 4.3 updated to the latest via Yum. I did yum groupinstall drbd-heartbeat and yum install kernel-module-drbd-kernel-module-drbd-2.6.9-34.EL to match my kernel. The problem I have is that on 1 machine drbd works fine, but when I start

hi, I was following this wiki http://wiki.centos.org/HowTos/Ha-Drbd for my CentOS 5 installation, but it appears that the kmod-drdb is not for the newest kernel. Would anyone know how long before this is updated? kmod-drbd i686 8.0.6-1.2.6.18_8.1.14.el5 extras kernel i686 2.6.18-8.el5 installed

Hi, sometimes, especially after a kernel upgrade, I need to reboot the xen host. All the VM''s are mirrored to another machine by using drbd. If the machine comes back after a reboot, the drbd devices are all in secondary mode, and therefore, the VM''s cannot start. I have to issue a "drbdadm primary" for every VM first. (I cannot use "drdadm primary all") Of
