BLUP with missing data
hello guys, I need to do a BLUP in the simplest model
y = Xm + Zg + e
however I have missing data in the analysis which I can?t consider as
0(zero). So I need to generate the matrix X'Z, Z'X and Z'Z step by step; I
can?t use
crossprod(x) #neither
X'X <- t(x)%*%x
because I should skip the elements with missing data in the matrix
I?ll try to be more clear,
supposing
a matrix x

Multivariate dispersion & distances
Dear All,
I'm using betadisper {vegan} and I'm interested not only in the dispersion
within the group but also the distances between the groups. With betadisper
I get distances to group centroids but is it possible to get distances to
other groups centroids?
It might be possible to do it by hand by the formula given in the
description of the betadisper (below) but I'm a bit confused

lmer - BLUP prediction intervals
Dear all
I have a model that looks like this:
m1 <- lmer(Difference ~ 1+ (1|Examiner) + (1|Item), data=englisho.data)
I know it is not possible to estimate random effects but one can
obtain BLUPs of the conditional modes with
re1 <- ranef(m1, postVar=T)
And then dotplot(re1) for the examiner and item levels gives me a nice
prediction interval. But I would like to have the prediction

Multivariate Poisson GLM??
Dear R Users,
I'm working on a problem where I have a multivariate response vector of
counts and a continuous predictor.
I've thought about doing this the same way you would do a Multvariate
regression model with normally distributed data, but since these data are
counts, they are probably better modeled with a Poisson distribution.
For example
y1<-rpois(100,3.5)
y2<-rpois(100,1.5)

Multivariate chi-square distribution function
Dear All,
Is there any function in R for computing "multivariate chi-square
distribution"?
How about "multivariate gamma distribution"?
I appreciate any comment on this subject.

better example for multivariate data simulation question-please help if you can
Dear?All,
?
a few weeks ago I have posted a question on the R help listserv that?some of you have responded to with a great solution, would like to thank you for that? again.?I thought I would reach out to you with the issue I am trying to solve now. I have posted the question a few days ago, but probably it was not?clear enough, so I thought i try it again.?At times I have a multivariate example

Discrete Multivariate Analysis (log-linear model)
I'm reading a old statistics book "MARVIN J. Karson (1982), Multivariate
Statistical Methods, The IOWA State University Press, Iowa". In the chapter
XI i can find some information about discrete multivariate analysis. This
chapter is restricted to an introduction to log-linear models for analysis of
multidimensional contingency tables. For example, in the log-linear model for

Multivariate Granger Causality Tests
Dear Community,
For my masters thesis I need to perform a multivariate granger causality
test. I have found a code for bivariate testing on this page
(http://www.econ.uiuc.edu/~econ472/granger.R.txt), which I think would not
be useful for the multivariate case. Does anybody know a code for a
multivariate granger causality test. Thank you in advance.
Best Regards

Simulation of Multivariate Fractional Gaussian Noise and Fractional Brownian Motion
Dear R Helpers,
I have searched for any R package or code for simulating multivariate
fractional Brownian motion (mFBM) or multivariate fractional Gaussian noise
(mFGN) when a covariance matrix are given. Unfortunately, I could not find
such a package or code.
Can you suggest any solution for multivariate FBM and FGN simulation? Thank
you for your help.
Best Regards,
Ryan

Doubly Multivariate LME
Dear R:
I am trying to fit a doubly multivariate LME (DM) where I have two response variables measured on two occasions per person. Specifically, reading and math scores measured at the beginning and ending of a school year. The response variables have a correlation of r = .85.
The response variables in the data matrix are stacked in a vector with a dummy code flagging each outcome and with

doubly multivariate analysis in R
20 subjects were measured in 5 conditions (thus repeated measures) and
for each subject in each condition there are 4 response measures (thus
multivariate as it is a combined score that needs to be compared across
the conditions).
So, using a multivariate approach to repeated measures this is a doubly
multivariate analysis.
I would appreciate any suggestions as to the best way to do such a

Multivariate discrete HMMs
Hi r-help,
I have been using your RHmm package for some time and have recently
had to try using the package for a new dataset.
Basically I have a dataset with a number of discrete observation
variables that change over time, and I would love to try modeling them
using a HMM.
Basically I was wondering if RHmm can be used to model a multivariate
discrete HMM, i.e., the observations are a vector

evaluation of discriminant functions+multivariate homoscedasticity
Hello,
I am switching from SPSS-Windows to R-Linux. My university is very
SPSS-oriented so maybe that's the cause of my problems. I am a beginner
in R and my assignments are SPSS-oriented, so I hope I don't annoy
anyone with my questions...
Right now I've got 2 problems:

I've simulated a longitudinal multivariate normal data set from which
I've simulated missing-patterns such as MCAR MAR and a simple kind of

trying to perform a T2-test as done in the multivariate case under th
