...gh) of the spectrum are still reliable with this circularity option? At the extremes, values seem to result from kernel application to collections of high and low frequencies. Related to this, shouldn't the frequency range shorten according to the size of kernel used? My doubt came from reading Diggle(1990) p105. e.g. data(lh) x<-spec.pgram(ldeaths, detrend=T, taper=0)$freq y<-spec.pgram(ldeaths, kernel("modified.daniell", c(6,6)), detrend=T, taper=0)$freq x==y Thanks in advance, Nuno Prista

Hi, I'm trying to figure out if there are any packages allowing one to fit mixed models (or non-linear mixed models) to data that includes censoring. I've done some searching already on CRAN and through the mailing list archives, but haven't discovered anything. Since I may well have done a poor job searching I thought I'd ask here prior to giving up. I understand that

There is quite good documentation (including a detailed introductory session). You can also join the R-sig-geo list https://stat.ethz.ch/mailman/listinfo/r-sig-geo and Paulo and other people will help you through. Ruben

Hi, Are there some texts about time series that teatches it with R? And site 'bout time series "for dummies" , can anyone indicate them for me? thanks a lot Rafael Bertola Undergraduate in Statistics at UNICAMP - Brasil -------------------------------------------------- --------------------------------------------------

hi all- I am doing some research, have never used R before until today and need to understand the following program for a project. if some one could PLEASE help me understand this program ASAP i would GREATLY appreciate it (any syntax/ statistic comments would be great) PLEASE PLEASE HELP!! THANKYOU!!! -on a side note, it seems to me that R doesnt include the pv, and it was calculated

...ion, and simple visual inspection reveals a very close correspondence between the two series, both of which show strong seasonality and also corresponding variation from year to year. My question is how to approach the analysis of these data using R. Here is what we have done so far (guided by Diggle and MASS): 1) Create two time-series (ts) objects from the data, making sure the corresponding observations in the two ts are in fact contemporaneous. 2) Decompose each ts into seasonal, trend and remainder components using stl() and decompose(). 3) Examine the cross-correlogram for the raw ts...

Hi, all, Have anyone used kringing included in R? How is it? Does it handle anisotropy data well? How does it compare with Kriging in Arc/Info? or other geostatistics software customized to do kriging or other geostatistics functions? I tried Easykriging, a geostatistics tool developed for Matlab. It has very nice GUI, but it does not provide library which i can call in my programs. so it is

Hi all, before I roll my own, naive implementation of a particular spatial point process, I thought I'd ask whether this has already been done. Specifically, I am looking for essentially the opposite of the Strauss and Mate'rn processes included in library(spatial) and documented in MASS. I am examining daily travel patterns, focusing on just the destinations of trips, not the

Dear all R users, I have a small doubt about panel data analysis. My basic understanding on Panel data is a type of data that is collected over time and subjects. Vector Autoregressive Model (VAR) model used on this type of data. Therefore can I say that, one of statistical tools used for analysis of panel data is VAR model? If you clarify my doubt I will be very grateful. Thanks and regards,
