Hi, I was playing around with something else and I noticed this matrix code for residuals in a linear model doesn't say what lm() says. Please tell me if I am completely misguided here. data(mtcars) Y <- as.matrix(mtcars[,1]) X <- as.matrix(mtcars[,c(2:11)]) # shouldnt this: H <- X %*% solve(t(X) %*% X) %*% t(X) (diag(dim(H)[1]) - H) %*% Y # be equal to this: residuals(lm(Y~X))

I'm new here, but I feel like chiming in, I hope my opinions are welcome. At first glance at this thread it seems unnecessary to argue about the necessity of these checks when when the option exists to give users the choice. Adding configuration option(s) for users who wish to bypass these checks could allow experienced users to do what they need to, and less experienced users could

During debugging of another problem I found that in x2APIC mode, the destination field of the low address value wasn''t passed back correctly. While this is benign in most cases (as the value isn''t being used anywhere), it can be confusing (and misguiding) when printing the value read or when comparing it to the one previously passed into the inverse function.

Just out of curiosity, can some please explain the following return NA. x <- 6 var(x) y <- c( NA, NA, 10000 ) var(y, na.rm=T) Unless I am seriously misguided, I believe that the variance of a single number (i.e. a constant) should be zero. Thanks. Regards, Adai.

Hi, trying to build the h323 channel driver that comes with asterisk works fine, but only as long as I use openh323-1.11.7. Unfortunately, that setup seems to have a bug which misguides one of the audio streams. (So while * can "hear" me, the phone remains silent.) I suppose that bug is fixed at least in openh323 CVS. At least, I got things mostly working using the external chan_oh323. That setup seems to drop small audio snippets like VoiceMail's password prompt, t...

Hi all, I'm trying to make an integer-backed quarter (as in fraction of year) class, but I can't quite it to work. I want integer-backed so I don't have to worry about floating-point effects when doing math, and so that I can use it as in data.table. First of all, is there a good reference for this anywhere? All of the S4 tutorials that I've found have been too high-level, and

Do you mean inttoptr here? And that "all pointer values that contribute (directly or indirectly) to the computation of the

Hello, I need to put a script in place for updating a local database with a remote resource periodically. It should be started alongside the server (or inside it, whatever) and be run as long as the server running my rails app is up an running. Any thoughts on how to accomplish this? I have thought of editing the environment.rb file and placing the call to the script trigger there, but I wonder

Hi I've used Wine for some time now, compiled from source, from root with no problems. I now wish to run it regularly as an ordinary user. Unfortunately it's refusing to run because "the socket is not owned by you", or words to that effect. After the socket is created under /home/user/.wine/... I can give it user permissions and Wine will start, but if I stop Wine and

Think I answered my own question really. The display in iTunes, for example, is swapping between what in status.xsl would be Stream Title and Current Song. If Song is updated like so: http://admin:password@myserver.pulverradio.com:8000/admin/metadata? mount=/high.mp3&mode=updinfo&song=ACDC+Back%20In%20Black ...then what exactly is the verbage to update StreamTitle?

Hi, I plot no: of bytes against time and find the distribution curve using R. These bytes are sent from the client to the server. Is there a way to generate bytes randomly using R according to a distribution ? I would like to send these bytes to the server. Hope I am not misguided here. My goal is to simulate a certain distribution of bytes. Thanks, Mohan DISCLAIMER:\

I am helping my wife do some statistical analysis. She is a biologist, and she has performed some measurements on various genotypes of mice. My background is in applied mathematics and engineering, and I have a fairly good statistics background, but I am by no means a PhD level expert in statistical methods. We have used the lmer package to fit various models for the various experiments that she

Hello everybody After doing a MANOVA on a bunch of data, I want to be able to make some comment on the amount of variation in the data that is explained by the factor of interest. I want to say this in the following way: XX% of the data is explained by A. I can acheive something like what I want by doing the following: X <- structure(c(9, 6, 9, 3, 2, 7), .Dim = as.integer(c(3,
