linear models and colinear variables...
.... The basic, all inclusive form looks like lm(mic ~ B * D * S * U * V * ICU) Where mic, U, V, and ICU are numeric values and B D and S are factors with about 16, 16 and 2 levels respectively. In short, there's a ton of actual explanatory variables that look something like this: Bstaph.aureus:Dvan:Sr:U:ICU There are a good number of hits but there's also a staggering number of complete misses, due to a combination of scare data in that particular niche and actual lack of deviation from the categorical mean. My suspicion is that there's a large degree of colinearity in some of these...

Security Guide for CentOS/RHEL
Is there a step by step approach to securing CentOS 4X (or even RHEL 4X)? I don't mean the stuff in the docs/security guide but a working step by step guide? There used to be packages like rkhunter and tripwire but I don't know if the ones in rpmforge/kbs repo are up to date. Thanks, Josh.

Extracted from http://www.centos.org/modules/tinycontent/index.php?id=16 I added no 3 above. I had not been on this mailing list or others for a while but I thought other newbies would benefit.

Backup and reinstall a CentOS server
I've got a CentOS server that crashes due to a bad hard disk. I have got a spare disk and need to format and reinstall CentOS from the SERVER CD. Backup and reinstall is a major PITA because of some of the customisations that I've done e.g. the DNS Server is set to log queries (the default does not do this).

Yumex-Error in loading repository data
On a CentOS 4 desktop Yumex gives the error message "Error in loading repository data" but yum works fine from the cli. Could something have been broken in yumex? Putting yumex in debug mode does not give me clues as to the error message. Thanks, Josh

Centos 4.7 delay more than mirror issue?
Hi folks, Normally people ask "when is CentOS 4.7 coming" and they are told "when it is ready".

I have not seen Johnny Hughes or even Dag posting on this list for some time. CentOS
