...ate a spectral coherence between two timeseries. The stats : spectrum() returns a coh matrix which estimates coherence (squared). A basic test which from which i expect near-zero coherence: x = rnorm(500) y = rnorm(500) xts = ts(x, frequency = 10) yts = ts(y, frequency = 10) gxy = spectrum( cbind( xts, yts ) ) plot( gxy $ freq, gxy $ coh ) yields a white spectrum of 1. Clearly i'm not using this correctly... or i mis-interpret the coh as a cross-spectral density estimate of coherence |Gxy|^2/(Gxx Gyy) Thanks in advance!

Thanks for you comments. I have the one port card now. I plan on purchasing the TDM400. My only question is whether or not the Dell optiplex has pci 2.1 (I think) I have one system running with the single port card. Today I received 2 sipura 2000 modules. Configured the first one tonight... Works great. Pat -----Original Message----- From: asterisk-users-bounces@lists.digium.com

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
