...amples have equal weights 1/n. The ECDF of these samples is defined as for example at http://en.wikipedia.org/wiki/Empirical_distribution_function and I can compute it using the ecdf() function in R. I define the 'ECDF' of the samples x with their associated weights in the following way: F_N(x) = 1/N * sum_{i=1}^{N}w_i * Indicator(x_i <= x) (does this 'ECDF' have another name???) So it's basically the same formula as the one on the above URL, but the only difference is that I multiply the indicator function for x_i with the weight w_i. Now suppose F_n(x) is the ECDF o...

Hola a todos: Tengo un problema con las fechas, básicamente necesito una diferencia en días y siempre se sale en segundos. Salvo un ejemplo copiado de un libro, pero yo necesito procesar los datos propios. Les paso el código en R (copiar y pegar, son solo dos días que se comparan) y al final como me salen los resultados porque es medio complicada mi redacción. ¿Alguna idea? fechas1

Dear R People, This question has nothing to do with R directly, but it is a simulation question. I need to generate a random variable distributed as gamma(\alpha,\beta), with the additional proviso that it must be a function of random variable(s) which do not depend on \alpha, \beta. In this case, I have \alpha = (T-1)/2, where T is a positive integer. So, it seems reasonable to first simulate

I'm a mathematician and programmer working on experimental surround sound techniques. Some of the ideas I'm working on require dozens of channels. These channels are often highly correlated and are very well suited to compression. I'm new to Vorbis. Does it attempt to address such issues?

Hi All I downloaded the binary package of Samba 2.2.2 on Friday from one of the Samba mirror sites, I think Belgium, and installed it on a Sun E450 running Solaris 2.6. Today everything has fallen flat on its face. Unfortunately I am on holiday this week so not able to deal with the problem directly, but via telephone calls. Apparently what is happening is that smbd is gobbling up all the

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
