Conditional Autoregressive Value at Risk (CAViaR)
Hi, I am trying to replicate Engle and Manganelli's paper Conditional Autoregressive Value at Risk (CAViaR) by Regression Quantiles. I have the Matlab code which I cannot get to work as I have never used Matlab before, does anyone know if there is the same code available to estimate the CAViaR models in R? Thanks, Shane -- View this message in context:

WD caviar/mpt issues
I know that this has been well-discussed already, but it''s been a few months - WD caviars with mpt/mpt_sas generating lots of retryable read errors, spitting out lots of beloved " Log info 31080000 received for target" messages, and just generally not working right. (SM 836EL1 and 836TQ chassis - though I have several variations on theme depending on date of purchase: 836EL2s,

One disk speed problem [SOLVED], and a question on hdparm
I believe I've posted before about one of the speed issues we were having, of backups taking many, many hours that should *not* take that long. My manager and I finally nailed it down to the h/d itself. Identical boxes, and he tried a backup of one system which took under two hours, while the same regular one rand nearly six. I'd been googling on and off for weeks, and this morning, ran

Race condition with mdadm at boot [still mystifying]
This is a bit long-winded, but I wanted to share some info .... Regarding my earlier message about a possible race condition with mdadm, I have been doing all sorts of poking around with the boot process. Thanks to a tip from Steven Yellin at Stanford, I found where to add a delay in the rc.sysinit script, which invokes mdadm to assemble the arrays. Unfortunately it didn't help, so it

sata_nv, CentOS 4 update 2 and hang during post-install
Good day. Thanks in advance for any help. I have a Tyan S2895 (Thunder K8WE) with 2 275 Opterons and the latest (1.02) bios. It appears to have an nVidia nForce SATA chipset which connects to a 250gb WD Caviar SATA drive. Using the CentOS 4 update 2 x86_64 DVD, the install is peachy until half-way through the "performing post install configuration" bit. Then it hangs forever. I

quantile regression - estimation of CAViaR
How is it possible to estimate the conditional autoregressive Value-at-Risk model qantile_t(tau)=a0+a1*qantile_(t-1)(tau)+a2*abs(r_(t-1)) see http://www.faculty.ucr.edu/~taelee/paper/BLSpaper1.pdf (page 10)) of Engle & Manganelli in R? The qantile_(t-1)(tau)-term causes headache. Kind regards, Jaci -- "Ein Herz f?r Kinder" - Ihre Spende hilft! Aktion: www.deutschlandsegelt.de

Odd issue with 7.7.1908 updated with qemu-kvm-ev
So, I have a client that has an internal use application that needs an ancient version of libc5.? That's not a typo; libc5.? Before the server that ran it died about a year and a half ago (said server was an AMD K6-2/450 with a 6GB Western Digital Caviar drive that had been spinning nearly continuously for almost 20 years!) it was running on Red Hat Linux 5.2.? The last version of CentOS

Hard disk recomendation for a software raid 5 array. Does Linux Software Raid support/interacts well with TLER enabled disks.
Hi people, I am building a cheap remote rsync backup server using a software raid 5 array of 4 500GB disks. What I have available on the market is: 1. HITACHI GST Deskstar T7K500 500GB 7200rpm 16MB cache Serial ATA II-300 2. SEAGATE Barracuda 7200.10 with NCQ 500GB 7200rpm 16MB cache Serial ATA II-300 3.

Still more questions WRT selecting a mobo for small ZFS RAID
Like many others, I am looking to put together a SOHO NAS based on ZFS/CIFS. The plan is 6 x 1TB drives in RAIDZ2 configuration, driven via mobo with 6 SATA ports. I''ve read most, if not all, of the threads here, as well as sbredon''s excellent article on building a home NAS, yet I still have a number of unanswered questions. I was leaning heavily towards the M2N-E for a while,

Best 1.5TB drives for consumer RAID?
Which consumer-priced 1.5TB drives do people currently recommend? I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap. As of Jan 2010 it seems the price sweet spot is the 1.5TB drives. As I had a lot of success with Western Digital drives I thought I would

Software RAID1 with CentOS-6.2
Hello, Having a problem with software RAID that is driving me crazy. Here's the details: 1. CentOS 6.2 x86_64 install from the minimal iso (via pxeboot). 2. Reasonably good PC hardware (i.e. not budget, but not server grade either) with a pair of 1TB Western Digital SATA3 Drives. 3. Drives are plugged into the SATA3 ports on the mainboard (both drives and cables say they can do 6Gb/s). 4.

4kB sector size HDDs
Hello again. Do any of you have one of the 'new' HDDs with 4kB Sectors currently in use? I would upgrade to the 4kB disks but I don't know if this might be problematic as I intend to use ZFS w/ RAIDz or at least a classic RAID6. How might this affect performance under 5.5 and how do I go about setting up the alignment of the partitions I use? Kind regards Dawid Horace

5-STABLE softupdates issue?
Greetings, out of fun and to investigate claims about alleged bgfsck resource hogging (which I could not reproduce) posted to news:de.comp.os.unix.bsd, I pressed the reset button on a live FreeBSD 5-STABLE system. Upon reboot, fsck -p complained about an unexpected softupdates inconsistency on the / file system and put me into single user mode, the manual fsck / then asked me to agree to

newer smartctl?
If y'all remember the problem I posted a while back, with a 3TB drive for userspace loosing it on a server, and spitting DRDY errors, but which work on everything else. Well, enough research, and conversation, and I may have found the problem: it's a Caviar Green, meant for a desktop, and the controller in the server has issues, because it uses TLER:

Error with 1.9.0 - Invalid HOMEDRIVE
I installed R project 1.9.0 on Windows XP. The installation went well. Then, I rebooted.

ISE review of I-D: deprecate command VER?
I received the following comment from the Independent Submissions Editor (ISE): The command VER is hazardous because it encourages exploiting of implementation peculiarities that are not well documented in a protocol.? The best example of such a failure is the browser version field in HTTP.? A complete disaster.? You should warn against use of this command, or even better, deprecate it.
