Stat 111’s history

• Usually co-taught with Neil Shephard
  • Currently on Sabbatical
  • Neil is the first joint professor in Stat and Econ
  • Joe and Neil are writing a Stat 111 book
• Blast from the past: Joe hasn’t taught in Hall C since before COVID
• Unfortunately, publishing the Stat 110 book tanked Joe’s teaching reviews
  • Because the book is the accumulation of Ed, teaching experience, etc.
  • And he wrote the book!
• Chapters 1-3 of the Stat 111 draft book are online
  • Roughly 1 homework per chapter
• Not as many practice exams for midterm/final due to changing course structure
