search for: denstiy

I have 10000 bivarate samples (x1, x2), and I want to estimate the marginal density of x2. I searched the R manual but couldn't find a function that can do this job. It seems "density" only works for single-variate samples. Can anybody help me with it? Thanks a lot! Best, J. Deng

I've been using the sm.denstiy.compare function and would like to know some specifics: a) What kind of bootstrap sampling is used, with or without replacement? b) A p-value is returned after running the following script (for example): library(sm) y <- rnorm(100) g <- rep(1:2, rep(50,2)) sm.density.compare(y, g, model=&qu...

I fitted a mixture denstiy of two gaussians two my data. I now want to calculated the standard errors of the estimates via the boot.se command of the mixtools package. My question is now, if the output is correct? It seems a bit odd to me, so is this correct what I am doing and can I rely on the values? My data: http://s000...
