Uniform Gaussian Kernel
...I have just based it on the Normal Distribution, but I'm not sure what I need to change to make it work. Where z is my vector. plot(0, 0, xlim=range(0, 300), ylim=range(0, 1), pch=NA,) for(i in 1:length(z)) { points(z[i], 0, pch="|") } x = seq(-10, 10, 0.01) for(i in 1:length(z)){ std_dev = 1 lines(x, dunif(x, z[i], sd = std_dev)) } Any ideas? Thanks. -- View this message in context: http://r.789695.n4.nabble.com/Uniform-Gaussian-Kernel-tp3495742p3495742.html Sent from the R help mailing list archive at Nabble.com.

lasso based selection for mixed model
Dear useRs (called Frank Harrell, most likely), after having preached for years to my medical colleagues to be cautious with stepwise selection procedures, they chanted back asking for an alternative when using mixed models. There is a half dozen laXXX packages around for all types of linear models, but as far I see there is none for mixed models such as lme. Even boot.stepAIC (which I
