[lme4]Coef output with binomial lmer
Dear R users I have built the following model m1<-lmer(y~harn+foodn+(1|ass%in%pop%in%fam),family = "quasibinomial") where y<-cbind(alive,dead) where harn and foodn are categorical factors and the random effect is a nested term to represent experimental structure e.g. Day/Block/Replicate ass= 5 level factor, pop= 2 populations per treatment factor in each assay, 7 reps

Problem on model simplification with glmmPQL
Hi all, I try to make a split-plot with poisson errors using glmmPQL, but I have some doubts about the model simplification. Look my system: Block = 3 blocks Xvar1 = 2 levels Xvar2 = 13 levels Yvar = Count data Response I need know about the behaviour of Var1, Var2 and interaction Var1:Var2. Look the levels: > levels(Xvar1) [1] "A" "B" > levels(Xvar2) [1]

Hartley's table
Hi, I used the commands below to make Hartley's table, but some values are NA. require(SuppDists) trat = seq(2, 15, 1) gl = seq(2, 40, 1) har = matrix(0, nr=length(gl), nc=length(trat)) for(i in 1:length(gl)) for(j in 1:length(trat)) har[i,j] <- qmaxFratio(.95, df=gl[i], k=trat[j]) rownames(har) <- gl colnames(har) <- trat head(har) The output (head): 2

CentOS village @ HAR
Hey I am just organizing the CentOS village at HAR and need a rough estimate of people who will be attending. What do people want? Shall the CentOS people have their own party tent? We are currently with the Fedora people. I will also post on the SL mailing list. Hope to see you all at HAR?

Preloading WINS registrations
I have a couple of Samba boxes, one of which is dedicated to WINS. The other I dole out anti-virus stuff to 3,500 odd PCs from. This second one will disappear from the WINS server from time to time which is a bit of a pain. I use nmblookup -R -U <wins_ip> <2nd_box_ip> to test for it. All clients are configured as "P" nodes so WINS is a bit essential. To bring it back I

Switching log(J) to log(J+1) to avoid log(0) in HAR-RVJ model
I am working with xts dependent data, and my code is as follows (the problem is explained throughout): dat <- getdat("prices") dat <- read.zoo(dat, sep = "",format="%d/%m/%Y %H:%M", tz="", FUN=NULL, regular=TRUE, header=TRUE, index.column=1, colClasses=c("character", "numeric")) dat <- as.xts(dat)

GLMMPQL spatial autocorrelation
Dear all, I am experiencing problems using the glmmPQL function in the MASS package (Venables & Ripley 2002) to model binomial data with spatial autocorrelation. My question - is the presence of birds affected by various hydrological parameters? Presence/absence data were collected from 83 sites and coupled against hydrological data from the same site. The bird survey sampling effort

Measuring the change in coupling of time series through time.
I am trying to work out what analysis to perform on two coupled time-series. I want to ask how the coupling (i.e. lag or correlation) changes over time. The time series are of 4 replicate pred-prey time series where the series appear more tightly coupled at peaks but drift apart during the decline and trough phases of the cycles. The time series are short (70-80 weeks/points replicated 4

Change log(J) to log(J+1) to stop log(0) from occurring in harModel
I think the code is part of the RTAQ package but is not included in it, as I obtained it from https://r-forge.r-project.org/scm/viewvc.php/pkg/RTAQ/R/HAR_model.R?view=markup&root=blotter&sortby=author&pathrev=1028. It is not my code and I make no claim to other's good work, and apologize if I should even be posting it I am not sure, but in the transform function it allows to

[LLVMdev] RFB: Would like to flip the vector shuffle legality flag
I filed a couple more, in case they're actually different issues: - http://llvm.org/bugs/show_bug.cgi?id=22412 - http://llvm.org/bugs/show_bug.cgi?id=22413 And that's pretty much it for internal changes. I'm fine with flipping the switch; Quentin, are you? Also, just to have an idea, do you (or someone else!) plan to tackle these in the near future? -Ahmed On Thu, Jan 29, 2015 at

[LLVMdev] RFB: Would like to flip the vector shuffle legality flag
I may get one or two in the next month, but not more than that. Focused on the pass manager for now. If none get there first, I'll eventually circle back though, so they won't rot forever.

R crash with modified lmer code
Hi all, I've now got a problem with some modified lmer code (function lmer1 pasted at end) - I've made only three changes to the lmer code (marked), and I'm not really looking for comments on this function, but would like to know why execution of the following commands that use it almost invariably (but not quite predictably) leads to the R session terminating. Here's the command

How do I normalize a PSD?
Dear Tom, Short answer, if your using spec.pgram(), use the smoothing kernel to get a better estimate at the frequency centered in the bandwidth. If your frequency bin of interest is wider than the bandwidth of the kernel, average across frequencies (I think). The estimate appears to be normalized already. If you are calculating your PSD independently, then oversample (e.g. 2, perhaps 4 or more
