Not convinced that responses so far have addressed the problem. The model is y = mu + U + e where e is a vector of independendent errors with variance ve, and U is a vector of random effects with covariance matrix va...

Dear Gabor Thanks very much. I knew about help(), but didn't know there was a help.search(). I have found what I was looking for by using it. Desmond Campbell Room C0.29, SGDP Centre Institute of Psychiatry, De...

Hi All, I am using "glm" function to build logistic regression. I noticed that glm function glm function is computing many other statistics which are not required for our analysis. As our dataset is very big and we have to...

Exactly what rule has been broken when lme (package nlme) produces the error message "Incompatible formulas for groups in random and correlation"? Here is what I am trying to do: lme(Y ~ trait-1, random = ~trait-1|sire, corr = corSymm...

The lmer function includes random terms as (expression for a model matrix|grouping factor) and I wonder how general the expression can be. For example, a pedigree object can be converted to an A matrix (in the language of animal...

Hello, I'm a student at the University of Klagenfurt / Austria and I need some help ! I have to predict 24 daily load-values. Therefor I got a dataset with following colums: 24 past daily load-values 6 past daily...

At the top of page 283 of Pinheiro and Bates, a covariance structure for the indomethicin example is specified as random = pdDiag(A1 + lrc1 + A2 + lrc2 ~ 1) The argument to pdDiag() looks like a two-sided formula, and I'm...

Dear R helpers, today I found something interesting in R. 0^0 gives value 1 in R. But it is undefined in mathematics. During debugging a R code, I found it and it effects my program severely. So my question...

Dear List, I have multiple time series, all of which (excepting 1) have missing values. These run for ~30 years, with monthly sampling. I need to determine stationarity, and have tried to use the Augmented Dickey-Fuller test (adf.test...

I've tried downloading SetupR.exe from the Bristol site and from the Vienna site, and in both cases the file appears to have become corrupted ... do you know whether other users have had similar problems?

i don't know, whether this is a bug or it is intended: when using winedt and R together it works perfectly, as long as R is run in mdi (multiple window mode). When you switch to sdi (single window...

Dear all, This is probably off topic, but I did not know where to turn and since most of you have an excellent knowledge of statistics, I thought of sending my question to this list. I was wondering whether there...
