Hello everybody, this is a bit off topic, so maybe you can just reply to me personally... What is the typical notation for 'skewness', 'kurtosis' and maybe 'excess kurtosis'? Thank you, Martina -------------------------------------------------------------------------- Department of Statistics Office Phone: (614) 292-1567...

Hello everybody, I would like to perform a test for normality (without specifying the mean a variance) on the sample data (80 observations). I found that Lilliefors test is appropriate. Does anybody have it programmed already, or is there a...

About my previous e-mail: I found a temporal fix to my problem by deleting some of the code in the C source file.

Dear all, is it possible to fit a following mixed effect model? Y_ij = mu + X_i * beta + b_i + b_ij + epsilon_ij b_i ~ Gaus [ 0, sigma^2 ] b_ij ~ Gaus [ 0, sigma_i^2 ] where i = 1...

It might not be the most elegant, but it works: > foo <- c(F, F, T, F, T, T, F ,T) > c(1:length(foo))[foo][1] [1] 3 > And if there is no 'T', it returns 'NA' > foo <- c(F...

Hello all, I would appreciate a lot your help - thank you... I have a problem with printing a jpeg pic of bwplots. I would like to have a background color "#E6E6E6" and all lines in graph color "#8c0200". ######################################### power.ch...

Hi all, I would like to draw one picture which would show two different types of boxplots using the same axes (kind of on top of each other). However, I would like to plot each boxplot using a different color...

I thank prof Ripley for prompt answer. I did delete the problem parts of the code in the C source file, which worked, but it slightly altered the library. I did not know that there is a possibility to use...

Hello all, I think that with the help of Mark Irwin, we solved the problem: We fit the model using glmmPQL and instead of using variable, 'state', we model the independent fixed-effect 'state' as I(x>10); i.e...

Dear R-helpers, I am trying to install Rstreams library on the following platform: ---------------------------- platform alphaev67-dec-osf5.0 arch alphaev67 os osf5.0 system alphaev67, osf5.0 status major 1 minor 2.3 year 2001 month 04 day 26...

Hi again, since the attached plots did not go through, I created a quick web-page, where all the plots are posted. Here it is: http://www.stat.ohio-state.edu/~pavlicov/levelplot/ Thanks again.

HI, try to use 'print.trellis()' Martina ----------------------------- see: library(lattice) trellis.device(bg="white") trellis.par.get("fontsize")->fontsize fontsize$default<-16 trellis.par.set("fontsize",fontsize) a<-c(1,2,4,5,4,3,3,3) b<-c(2...

Hi all, I encountered a difference between versions 1.6.1 and 1.7.0 when using levelplot with an option 'at'. Here are the specs of the two platforms used: > R.version _ platform sparc-sun-solaris2.8 arch sparc...

Thank to Deepayan Sarkar I can report that the levelplot works properly at 1.8.0 (I dont know more specs). Prof. Riply correctly noted that I did not mention what version of 'lattice' library I am using. Here is...

Hello, I have a dataset concerning slugs. For each slug, the number of pumps per one time slot was counted. The number of pumps follows Bi(30, p) where p is very small, thus could be approximated by Poisson dist...
