Sneaking Into A Campus Tour

  • Hosts joke about traditions like rubbing (not licking) the E. coli turtle on the quad to illustrate campus rites.
ANECDOTE

Youthful Boasts And Fisher's Early Work

  • The hosts compare youthful achievements: Patrick saw Van Halen; Gregg grew an orange mustache and got kicked out of an honors program.
  • They introduce R.A. Fisher as an early achiever who developed ANOVA and ideas behind maximum likelihood in his twenties.
INSIGHT

Flip The Probability Question

  • Maximum likelihood picks parameter values that make the observed data most probable rather than asking how probable data are given fixed parameters.
  • Seeing bus #27 implies the MLE for total buses is 27 because that maximizes the likelihood of observing 27.
