Hi, I tried to simulate an ARIMA model by using arima.sim(), say arima.sim(n=100,list(order=c(1,0,1),ar=0.6,ma=0.9,sd=1), but the acf and pacf of simulated data using acf() and pacf() are so much different from the theoritcal acf and pacf. For instance, in my case, ar=0.6 and ma=0.9, so the acf for all lags should be greater than 0 based on the theoritical calculation, but the acf of simulated data always has some negative values which bothers me. Can any one tell me why? and how can I get the simulated data close to...

If you want to quiet it down until it will be "fixed" properly, you can apply patch from http://lists.freedesktop.org/archives/nouveau/2010-July/005994.html Marcin

Hi, I''ve still have problems with ACPI(?) on Xen. After some system startup or resume CPU temperature goes high although all domUs (and dom0) are idle. On "good" system startup it is about 50-55C, on "bad" - above 67C (most time above 70C). I''ve noticed difference in C-states repored by Xen (attached files). On "bad" startups in addition suspend
