Variance Inflation factor

Hui Du
Hi All,


I need to calculate VIF (variance inflation factor) for my linear regression model. I found there was a function named  vif in 'HH' package. I have two questions:


1)      I was able to install that package in my R under windows. But while trying to install that package in UNIX, I got error:

Package HH is not available.

            Does somebody know why?


2)      Does somebody know the other way to calculate vif in R?


Many thanks.
HXD

Thanks. But in UNIX side, I got the same error

In getDependencies(pkgs, dependencies, available, lib) :
  package ‘car’ is not available

Richard M. Heiberger
In reply to this post by Jorge I Velez
Hui Du,

There is probably something wrong with either your setup or your choice of
CRAN
mirror.  Both HH and car are present in CRAN for all platforms.

---Your session info just arrived. "R version 2.11.1 (2010-05-31)" is over
two years old.
The current version is "R version 2.15.1 (2012-06-22)".
Upgrading R to the current version is recommended.
There might still be a problem with your setup as both HH and car worked
with 2.11.1.

You're rather out of date with your version of R -- if you want to use
the CRAN binaries provided by install.packages(), you usually have to
be at most one minor rev behind.

Try install.packages("car", type = "source")

But even better -- update to a poppin-fresh R 2.15.1: you get
parallelization, a byte-code-compiler, and all sorts of other goodies.

Best,
Michael

Thanks, all. I will upgrade my R in linux but I suspect the root cause is some set up problem although I don't know how to trace it yet. I am not that familiar with R in Linux. If somebody could give me a clue how to diagnose this kind of problem, that will be great.

Re: Variance Inflation factor

Michael Weylandt
Which Linux are you running?

For distros with package managers, that's usually all you need. Also Check up on the R-SIG-Debian (including Ubuntu) or R-SIG-Fedora as appropriate if you need more help.
