CentOS 6 supported hardware
Has anyone seen a supported hardware list on CentOS 6? I've been looking around for the last few days; even looked at RedHat's site but didn't find one. I've got a Dell Inspiron 1501 with a Dell Wireless 1390 WLAN mini-card in it and I'm trying to find out if it's going to have native driver support for the WIFI. thanks, -- Mark Weaver Computer Information Systems

Help to write to a file
Dear all: I am having some problems to use the function "sink()". Basically I am doing a loop over two files which contain unit-root variables. Then on a loop, I extract every i element of both files to create an object called z. If z meets some requirements, then I perform a unit root test (ADF test), otherwise not. As this process is repeated several times, for each i I want to get

Dickey Fuller test of a time series (problem)
Hi all, I tried to do a Dickey Fuller test with R using adf.test with a time series of german stock prices. I have 10 stocks from 1985 to 2009 with monthly stock prices. So if you do the math I have 289 values for each stock. I tried to do the test for each stock alone and had the 289 values of my first stock listed in R. When I tried to do the test with command adf.test(x, k=1) the following

nls with plinear and function on RHS
Dear R gurus, As part of finding initial values for a much more complicated fit I want to fit a function of the form y ~ a + bx + cx^d to fairly "noisy" data and have hit some problems. To demonstrate the specific R-related problem, here is an idealised data set, smaller and better fitting than reality: # idealised data set aDF <- data.frame( x= c(1.80, 9.27, 6.48, 2.61, 9.86,

Using Apache 2.2 config files on Apache 2.4
Hello List, I'm in the process of migrating LAMP servers. I've got a C5 LAMP server in my rack that has been running faithfully without complaint for the past 9 years. In some ways I really hate to move out of it, but there are things to get done, things to consider and reasons that make the migration necessary. I've got a C7 server loaded and the basic configuration partially

Scaling Statistical
Short question: Is it possible to use statistical tests, like the Augmented Dickey-Fuller test, in functions with for-loops? If not, are there any alternative ways to scale measures? Detailed explanation: I am working with time-series, and I want to flag curves that are not stationary and which display pulses, trends, or level shifts. >df DATE ID VALUE2012-03-06 1

Hello. I am still a newbie in R. Excuse me if I am asking something obvious. My efforts to get an answer through browsing the mailing archives failed. I want to perform an augmented Dickey-Fuller test and to obtain AIC and BIC and to be able to impose some linear restrictions on the ADF regression so as to decide the correct order of autoregression. However I could find no obvious way to impose

lag orders with ADF.test
Hello! I do not understand what is meant by: "aic" and "bic" follow a top-down strategy based on the Akaike's and Schwarz's information criteria in the datails to the ADF.test function. What does a "top-down strategy" mean? Probably the respective criterion is minimized and the mode vector contains the lag orders at which the criterion attains it
