Hi Guys, It is very simple question, but I can't find the answer! Please help me. I use R and such simple function as length() doesn't work. The result is always 1 even if my data are more then 1 observations! Do I have to load any additional library? > length(Ret_1) [1] 1 > length function (x) .Primitive("length") Thank you!!! -- Best regards, Andy Fetsun

Hi, Could you please help me with EGARCH and GJR? Is it possible to use EGARCH and GJR in R? I have used below mentioned code for GARCH in R, but I never used EGARCH and GJR in R. Thank you in advance! daten<-read.table("H://Daten//Zeitreihen//dax_1.csv", sep=";", header=T) DAX.kurs<-daten DAX.kurs<-ts(DAX.kurs,names="DAX-Kurs")

Dear Colleagues, I have faced with the problem that function rollaply with rolling window for calculation of volatility doesn't give the all results of calculations. I have run the rolling window for calculation in Excel and obtained that the number of outputs for Excel is 36 and for R is 18. The total number of observations is 37. In the attachment you can find pdf of the Excel and Excel

Dear Specialists in R, May be somebody has experiment in using pakage for the book Quantitative Risk Management by McNeil? This package is writen in R.

Operating system virtualization is the most effective way to utilize your system resources, jails let you setup isolated mini-systems. Jails are explains well in handbook however, from practical standpoint of view, the presented material is incomplete. The post below setup few scrips that follow handbook's 'Application of Jails' article and enhance with few missing features

After some poking into psm.c code I've got some results. First, for the archives, debug.psm.loglevel tunable is much more useful than a verbose boot for debugging PS/2 mouse issues. A good value is 2. Second, I fiddled with various probe methods to force them to "recognize" my mouse (by loosening their checks) and found out that the mouse works perfectly if it is treated as

Hi All, I have what I think is a ZFS related bug. Unfortunately my simplest test case is a bit cumbersome and I haven't definitively proven that the problem is ZFS related. I'm hoping for some feedback on how to move forward. Quick background: I rip my CD's using grip and produce flac files. I tag the music using Musicbrainz' Picard and transcode it to mp3's within Picard

I've just realized that I see in releng/7 something that I did not see in releng/6 - even if I use a file with custom rules in firewall_type I still get default loopback rules installed. I think that this is not correct, I am using custom rules exactly because I want to control *everything* (e.g. all deny rules come with log logamount xxx). -- Andriy Gapon

Hi Nouveau Team, I have the following hardware/software spec: ThinkPad T61 FreeBSD 7.1-RELEASE-p5 amd64 NVIDIA Quadro NVS 140M X driver nouveau External monitor NEC MultiSync 90GX2 I am connecting external monitor through VGA interface. I was able to detect it using command 'xrandr -q' and even turn it on: $ xrandr --output VGA-0 --auto --below LVDS-0 the geometry of my desktop

This is a fairly standard and old machine with 2 COM ports. Recently (last Friday) I decided to update my RELENG_7 system and also to transition from sio to uart. This what I had before the upgrade: kernel: sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 kernel: sio0: type 16550A kernel: sio0: [FILTER] kernel: sio1: <16550A-compatible COM port> port

I wouldn't report this if not for one coincidence (which is described below). I have too little facts, so this is more of a mystery problem tale than a real problem report. There are two systems: 1. old, slow, i386, UP, 7-STABLE 2. new, fast, amd64, MP, 6.3-RELEASE Systems are located at different physical locations. What is common between them: 1. they both have the same backup strategy

Hello everyone, I'm unable to read temperature Gigabyte H77-DH3H motherboard. Is that motherboard supported or am I doing it incorrectly? When trying to access hw.acpi.thermal everything appears to be ok, but it is not, the system always returns 27,8C and 29,8C which fooled me initially - the values never change. Here is output: [chinatsu]:/root# sysctl hw.acpi.thermal

Hello, Since FreeBSD 9.1 I have strange problems with the distribution. Some servers are rebooting without any kernel panic, instanly. First i thought it's a problem with my KVM system, but one of my FreeBSD under a Dell R210 have the same problem. The servers concerned are now: - Monitoring server - LDAP test server - Some other servers, randomly (not in production). First i thought it's
