Do the following:
www.google.com - search for "logistic regression".

groups.google.com/advanced_group_search?q=group:*Excel*&num=100 -
search for "logistic regression".

Having done these two simple things, I now know what logistic regression
is, and the first five posts in the group search gave me an
understanding of how to implement it in Excel.

You should be able to figure it out very quickly.
