Your group projects are due. Would you be kind enough to
submit those, please?
I'll be sending those along to Dave, so please send me
an electronic copy, if you would.
Last time:
We derived the linear regression equations, using multivariate
calculus
You had a few moments with your groups, in preparation for
today's report.
Today:
We derive the linear regression equations, only using linear algebra.
You have a new homework problem (due Wednesday), related to doing
a regression -- By hand!

"The
IPCC stands by its equation of 450 ppm = 2 degrees C [of
warming]....": For years scientists have said that if
atmospheric levels of carbon dioxide reach 450 parts per million (ppm)
the planet would heat up by an average of 2 degrees Celsius above
pre-industrial levels. They have also said that if the world crosses
that threshold, ecosystems worldwide would suffer serious damage.
