I was just curious about the logistic distribution, so I dug up a few points of interest. These are not critical. Especially do not confuse this with other uses of logistic that come up later in the course.
From Wikipedia, the logistic distribution is used to calculate chess ratings:
Τhe United States Chess Federation and FIDE have switched its formula for calculating chess ratings from the normal distribution to the logistic distribution; see the article on Elo rating system (itself based on the normal distribution).
The logistic distribution is easier to work with than the normal distribution. There is a formula for its cumulative density function that does not require approximation on a computer.
