This week we will cover the practical application of Bayesian statistics. Bayesian statistics is frequently and centrally used in medical, psychology, sociology and other analysis areas.
This is a very timely topic, because a NEO'er is currently on a Jeopardy winning streak, using controversial methods that he developed using a Data Science like approach. He developed a strategy based on game theory and informal statistics. It looks strange and controversial to the audience, but he keeps winning. He explains it here:

Mr Chu mentions that getting 'daily doubles' is a key part of his strategy.
The IBM Watson computer Jeopardy champion used Bayesian statistics to guess which square the daily double was likely to be on:

We will also review some material from Chapter 2.

One of the review items from last week was on how to do pivot tables in SQL. These 2 links below give good examples of what pivot tables are, and how to create them in SQL using 'group by':

MSSQL and Oracle have 'pivot' commands to aid in creating pivot tables:

I will be attending in spirit. If there is any way to get a Google Hangout or other conference setup happening, I'd love to listen in.

We just grab a coffee and speak French. Some people have been coming every week for months... it creates a kind of warmth to the group.
