Hello: I found that Amazon cannot find a copy of "Statistical Models in S"? I am about to embark on some tree-based and perhaps ANOVA models and have following options: (*) Find another book/online doc that covers this material (perhaps one recommended on the R FAQ page) (*) Use R documentation (*) Try even harder to land the white book. I have a decent conceptual and

Has anyone got Bastille-linux running on Centos-5.6? http://bastille-linux.sourceforge.net claims RHEL5 support but I ran into problems running it on a Centos 5.6 test system. First I had to "ln -s /usr/lib64/Bastille /usr/lib" just to get it to run at all. Then I tried faking /etc/redhat-release with Red Hat Enterprise Linux Server release 5.6 ... but I get this (why would it want

Hi, I swear I have read almost all the posted messages about this issue, but it's evident I couldn't find an answer (surely esay) to my problem. What I want is the following: Make 8 days aggregates from a daily series like this (dput output): structure(c(6.91777181625366, 0.79051125049591, 9.00625133514404, 9.86966037750244, 14.4326181411743, 3.70155477523804, 9.67768573760986,

We just started seeing the errors described in <http://bugs.centos.org/print_bug_page.php?bug_id=5575> The question is, given that we're not seeing DRDY errors, and this is showing on all four drives, and there's no RAID, should we just turn off SMART, or is this telling us something important, other than the bug? mark

This has been puzzling me for some time and despite bothering Auntie Google rather a lot, I've yet to find a satisfying answer. As an old-time (since 1981) unix and X guy, I've generally been fairly well-able to get fonts to behave in a rational manner. My needs are pretty simple - I just want 8-point (or 9-point etc) fonts to appear on the screen as 8-point font - ie more or less 8 *

How can I solve this error. Pl any one help me. with warm regards, Rajesh Rajesh Prakasan Sr. Data Centre Executive DIREM

Hi there We have a pair of servers running FreeBSD 9.1-RC3 that act as transparent layer 7 loadbalancer (relayd) and pop/imap proxy (dovecot). Only one of them is active at a given time, it's a failover setup. From time to time the active one gets in a state in which the 'thread taskq' thread uses up 100% of one cpu on its own, like here: ---- PID USERNAME PRI NICE SIZE

Hi, I'm facing an issue with at least two Samba servers in production both showing important number of log entries like: smbd[27355]: PANIC: assert failed at smbd/oplock.c(149): exclusive_oplocks_open>=0 Looking at the source code, this panic is triggered when the number of exclusive oplocks for a given file becomes negative. Once triggered for one smbd process, this process can

Hello, I?ve got a statistical problem that I hope you can help me with. It doesn?t have to do directly with R, so if there?s another forum which would suit better, please tell me! Now here?s the problem: I want to derive confidence intervals for a variable X, which is - given the descriptive statistics - obviously negatively skewed and leptokurtic (i.e. peaked). My aim is to make a statement

Hi, I'm new to R so please fogive if I write someting silly ... I need to recode a series of responses from a number of questionnaires. The data is read via ODBC from a database where all responses are coded as tables of the form (id, question, score). After dealing with recoding of missing values, I need to "invert" the scores of some questionnaire's item in the form x <-

I just got the list confirmation and noticed it''s text only email so here it is again in plain text. Below is the oringal message. Hi all, I am really struggling with this one, I have built a lot of linux machines using IPSEC tunnels and shorewall gateways. I decied to build a new test machine with Debian running 2.4.25 and Shorewall 2.0.15. I have two subnets on their own switches and

Satistics counters is useful for debugging and performance optimization, so this patch lets virtio_net driver collect following and export them to userspace through "ethtool -S": - number of packets sent/received - number of bytes sent/received - number of callbacks for tx/rx - number of kick for tx/rx - number of bytes/packets queued for tx As virtnet_stats were per-cpu, so both

Hi, This problem may be very easy, but I can't think of how to do it. I have constructed histograms of various variables in my dataset. Some of them are negatively skewed, and hence need data transformations applied. I know that you first need to reflect the negatively skewed data and then apply another transformation such as log, square root etc to bring it towards normailty. How is it

Dear Rers, I have threes series, x, y, z and I want to fit a model z ~ x + y. First of all, I fit a lm. I found the residuals are correlated, by looking at the acf() and pacf(). Then I tried to fit a gls model allowing residuals to be correlated (correlation = corARMA(p=5, q=1)): y.na <- as.data.frame(y[complete.cases(y),]) y.gls <- gls(z ~ x + y, data = y.na, correlation=corARMA(p=5,

I''m trying to figure out how to use ActiveRecord in conjunction with ARel. In particular, I''d like to replace my residual literal SQL with ARel, if only I could see how. Let''s take Article with multiple Versions as an example. With ARel alone, I can find articles with their latest versions like this articles = Article.arel_table versions = Article.arel_table

Hello list, I am trying to test a model but for the beginning I want to do this by using simulated dataset. The model is Y_t = X_t %*% beta + e Where Y : (Nx1); X: (Nxp); beta: (0.6,0.3,0.1); e-uncorrelated normally distributed variates for each t. and later I want to use to use this dataset in a BUGS model to estimate the betas. Thank you for you consideration. [[alternative

Hi, I would like to specify a spherical correlation structure for spatially autocorrelated residuals in a model based upon the logistic function of a response that is a proportion (0 to 1) (so usual binary logistic regression is not an option). There is no need for a g-side random effect with grouping in this model. Am I correct that nlme requires this (meaning a correlated error structure only
