Hi, does anybody know of a nice test to detect trend turning points in time series? Possibly with reference? Thanks, joerg

Hi all- I fit a zero-inflated Poisson model to model bycatch rates using an offset term for effort. I need to apply the fitted model to a datasets of varying levels of effort to predict the associated levels of bycatch. I am seeking assistance as to the correct way to code this. Thanks in advance!

Hi to all developer, sure that I will not be the first one with this idea but I did not found treads about this. I realized that there are some user interfaces like Brodgar and SciViews. There was used a lot of manpower to develop those programs. On the other side I realized that it could be very helpful to have such programs if somebody would like to change the statistical software from SPSS or other commercial software to R-Statistic. The first steps would be mor...

...onsequence of all this reading I am a bit confused. At first I gathered that there was no GUI for R, that R was strickly a CLI language. What brought me to that conclusion is the fact that on the R-project pages they refer the readers to external builders of GUIs like the R-Commander of John Fox, Brodgar, TeXmacs, SciViews etc.. On the other hand searching the mail archives for the word "R-GUI" yielded well over 500 hits. After reading a few tens of those I realized that there existed, after building R, an executable called "Rgui.exe", what is that? is that a GUI version of R...

I'd like to estimate time varying coefficients in a linear regression using a Kalman filter. Even if the Kalman Filter seems to be available in some packages I can't figure out how to use it to estimate the coefficients. Is there anyway to do that in R? Any help appreciated Thanks

Dear all, I'm a beginner of R and I need to carry out some three-way mixed ANOVAs. Following examples at http://personality-project.org/r/r.anova.html, I managed to get the ANOVA part, but I don't know how can I check data normality and homogeneity of variance in R (since they're the required assumptions of ANOVA analysis). Are there any special command/packages? Could anyone give me

Let me start with an example: par(mfrow=c(2,3)) for (i in 1:5){ x = rnorm(100) y = .5*x + rnorm(100, 0, sqrt(1-.5^2)) plot(x,y) } Note that there's five plots and six spaces for those plots via mfrow, leaving one row empty. Is there a way to have the bottom two plots centered? I think it looks weird to have them left-justified. Thanks in advance for the help! -- Dustin Fife PhD
