I am having problem using output of lm() function for further analysing using systemfit package. Basicaly, the problem s following - I generate several formulas using lm() > fo1 <- lm(r98[,2] ~ f98[,1] + f98[,2] + ... + f98[,43]) > fo2 <- lm(r98[,1] ~ f98[,1] + f98[,2] + ... + f98[,43]) and than I want to estimate a general model using package systemfit. > fitsur <-

I am having following problem: I?m constructing model for calculation of area of triangle. I know sides a, b, and gamma angle. I wish to calculate the area using heron?s formula: S <- sqrt(s*(s-a)*(s-b)*(s-c)) where s <- (a+b+c)/2 and c is calculated using law of cosines: c <- sqrt(a^2 + b^2 -2*a*b*cos(gamma)) since i am calculating a regression model, i need derivation of this

Hi, I have a dataset and I want to fit a function to it. The function is variogram model (http://en.wikipedia.org/wiki/Variogram) The variogram model is defined by three parameters and I want them to be automatically optimized for real time data. I tried to use gafit {gafit} for this, but there are some data configuration, where optimal results given by gafit() are negative, which is not correct

I've got the graphic with this: a=c(120,40,75,85,55,75,55,90,90,55,155) plot(ecdf(a)) How can I draw lines to show the lower quatile and upper quartil? I only know there is the argument lines(), but I don't know how to use it -- View this message in context: http://r.789695.n4.nabble.com/How-can-I-draw-a-line-in-empirical-distribution-function-tp3090675p3090675.html Sent from the R

Hi. I use winbind + squid on Debian Buster to authenticate users + authorize them based on groups they are in. It all works, well, good, but winbind's CPU utilization peaks can reach up to 100%. The same solution ran OK on Debian Jessie with up to 20% CPU utilization at most. The configuration of Buster must have been updated based on the samba version leap/shift compared to Jessie. On

Hi, I installed absolutely new installation of CentOS 4.3 from DVD media and I unchecked every additional packages.

Hi all, I'm working with a bunch of large graphs, and stumbled across something useful. Probably many of you know this, but I didn't and so others might benefit. Using pch="." speeds up plotting considerably over using symbols. > x <- runif(1000000) > y <- runif(1000000) > system.time(plot(x, y, pch=".")) user system elapsed 1.042 0.030 1.077

Hello, I do not have any statistical background, So I shall apologise if I am asking trivial question or help. I am trying to work with R. The problem I have on hand is: I have 2 sets of data(means & SD for each sample in the group of both sets). The sample size is massive(2000+ in each grp). I have a new set of experimental data and I like to classify this to either of the grps based on

I was wondering about general stability of glusterfs on 32 bit x86 Linux. I have it running without problems on some lightly used 32 bit systems, but this scares me a bit if I decided to use it in production[1]: While the 3.x versions of Gluster will compile on 32bit systems we do not QA or test on 32-bit systems. We strongly suggest you do NOT run Gluster in a 32-bit environment. I was

In order to be meaningful and usable together with other measuring methods, their use in my opinion should impose as little overhead as possible. With that, I wonder why per-cpu counters use atomic operations.

Hello, (1) what is the way to use table for the hole dataSet ? I would get a cross-table with x1 and other variables in the dataSet which have got 100 columns : table(x1,data[variable2 until variable 100])/length([variable2 until variable 100])*100 like this but it's wrong ? table(x1,data[,2:100])/length(data[,2:100])*100 if i type: table(data[,1:10]) to get the frequency
