March Madness

Regarding the NCAA basketball tournament, there has been a lot of talk about poor officiating and missed calls. People are calling the referees blind.


No wonder poor papers sometimes get published in top academic journals--they use double-blind referees.

Datastream

Thompson Reuters' Datastream product is one of the most comprehensive and most commonly used sources of international data.  Many researchers, however, complain about its slow speed and cumbersome interface.


Thompson Reuters should come up with an improved version, and that product should be called Datariver.

Perspectives on Dummy Variables

Stan Coleman, Trainer, Variable Special Forces:
"The life of a dummy variable is quite hard. These variables need to maintain strict focus their entire lives--they can only take values of zero or one. Can you imagine a continuous random variable doing that? They can't! It's impossible--probability zero."


Susan Gustafson, Primary School Teacher:
"I just don't understand the hype about the dummy variables. I've had many dummy variables come through my classroom. While I didn't know at the time they would grow up to become dummy variables, I distinctly remember many of these students. They were not at all interested in broadening their horizons. Forget trying to teach anything other than the Natural numbers to those students."
