Where I could find good documents about odds?
(naturally free)
I'm starting a University Course about odds and odds-ratio and their
use on Statistics Regression
Probably I'll use R-software for practise

I responded in one of the other groups you posted to.

If you are going to post the same thing to multiple groups, note that
cross-posting is preferable to multi-posting. You can read about the
difference between the two here:

I wasn't sure what the OP was asking and I don't use R-software, so
I just let the post go.

My IE browser for some reason couldn't access that URL:

$> Internet Explorer cannot display the webpage

So I'll just stick in my one LINE:

If p is a probability, then ODDS (in favor) is p/(1-p)

One can convert odds to p just as easily. So I don't really know
what's puzzing the OP and why a whole webpage is necessary to
explain the simple concept. :)

What am I missing?

It's just a page that explains that cross-posting means listing all the
groups on the Newsgroups: line of a single post, whereas multi-posting
is posting of individual copies to each group. It also says that if you
must post the same thing to more than one group, cross-posting is better
than multi-posting.

So I'll just stick in my one LINE:

As noted above, the page I pointed to in *this* group has nothing to do
with odds or odds ratios. It was meant to inform the OP about the
distinction between cross-posting and multi-posting.

In the *other* group, I directed the OP to a page on Steve Simon's
website that gives examples of odds ratios.

I agree completely that the
concept of odds is very straightforward. Nevertheless, I find that
beginners can still struggle with the concept of the odds ratio. I
thought examples might be helpful to the OP.
