Dear AllStat:
Version 2.2 of RegressIt, a free Excel add-in for linear regression and
multivariate data analysis, has just been released at
http://regressit.com. Its graphical output for regression is designed
to be superior to what is provided by commonly used statistics packages
and programming languages (and vastly superior to Excel's analysis
toolpack), and it includes a number of unique features that help to
teach and support best practices of data analysis. It's also fun to
use. Regression output worksheets include many live formulas as well as
interactive presentation-quality tables and charts. If you are a PC
user who applies or teaches linear regression or descriptive data
analysis to any extent, RegressIt will probably make a good companion,
if not substitute, for some of the software you are currently using.
Take it for a tour--it's offered for free as a public service--and
please share the link with your colleagues or students if you enjoy it.
Best wishes,
--Bob
