betabinomial model
Hi, can anyone help me fit betabinomial model to the following dataset where each iD is a cluster in itself , if i use package aod 's betabinom model it gives an estimate of zero to phi(the correlation coeficient ) and if i fix it to the anova type estimate obtained from icc( in package aod) then it says system is exactly singular. And when i try to fit my loglikelihood by

lme4 exactitud
Tengo una duda, hay unos modelos mixtos que se resuelven con lme4, no tengo problemas con esto, pero necesito tener el resultado para cada uno de los factores, lo expreso con este ejemplo aunque no es código r creo que se entendería Factores como ser casa y auto, tengo casa 1, casa 2, casa 3, y auto 1, auto2, auto 3. Con lme4 y utilizando ranef obtengo por ejemplo Casa 1

Coefficients of a factorized polynomial
Hi all, starting from a vector "v[1:n]" I would like to compute the coefficients of the polynomial (1+x^v[1])*(1+x^v[2])*...*(1+x^v[n]). The following code works but is extremely slow for a large "n" due to, I believe, the polynomial being factorized. I wanted to try the package "polynom" command "unclass" but I could not figure out how to input a

error bars in matplot
Hi, I was trying to get error bars in my matplot. I looked at an earlier thread, and the sample code that I made is: #------------------ library(plotrix) mat1 <- matrix(sample(1:30,10),nrow=5,ncol=2) ses <- matrix(sample(1:3,10,replace=T),nrow=5,ncol=2) vect <- seq(20,100,20) rownames(mat1) <- rownames(ses) <- vect colnames(mat1) <- colnames(ses) <- letters[1:2]

R package dependency issues when namespace is not attached
I have always assumed that having a package in the 'Depends' field would automatically also?import?the namespace. However, it seems that in R 2.15, dependencies do not become available until the package is actually?attached?to the searchpath. Is this intended behavior? The problem appears as follows: Suppose there is a package 'Child' which?Depends, but does not explicitly

steadily increasing/high loadavg without i/o wait or cpu utilization
Hi all, I just installed centos 5.4 xen-kernel on intel core i5 machine as dom0. After some hours of syncing a raid10 array (8 sata disk) I noticed a steadily increasing loadavg. I think without reasonable i/o wait or cpu utilization the loadavg on this system should be very lower. If this loadavg is normal I would be greatful if somone could explain why. The screenshots below show that there is

Two-factorial Huynh-Feldt-Test
Hi, I'm currently working on porting some SAS scripts to R, and hence need to do the same calculation (and get the same results) as SAS in order to make the transition easier for users of the script. In the script, I'm dealing with a two-factorial repeated-measures anova. I'll try to give you a short overview of the setup: - two between-cell factors: facBetweenROI (numbering

Multiple XY Lines Plot
Hi list, I’m trying to plot lines in the same graphic. There are lots of similar topic on the list history. I’ve read about xyplot (lattice) and other ways to do that but I only got complex error messages, and wasn’t able even to start a decent R scrip. Well I have some paired information (each H W ), were H is the y axis and W is the x axis, how could I plot all the four lines at the same image?

Skewness of fitted mixture not correct?
I fitted a gaussian mixture to my financial data. The data can be found here: http://uploadeasy.net/upload/32xzq.rar I look at the density with plot(density(dat),col="red",lwd=2) this has a skew of library(e1071) skewness(dat) -0.1284311 Now, I fit a gaussian mixture according to: f(l)=πϕ(l;μ1,σ21)+(1−π)ϕ(l;μ2,σ22) with:

Filling a variable with unmentioned categories
Hello, list,   I've been struggling with this task for a while looking for an efficient way to solve it: There are two variables 'price' and 'mentioned'. I want to 'enlarge' data so that missing price points within the price range are added to variable price. Also variable 'mentioned' is to receive values 0 in these cases. Note: Price points in original data can
