Data 102: Inference

Data102 Notes #

Here are my notes for the Fall 2022 offering of Data 102, Berkeley’s Inference for Data Science course.

Data 102 explores two major concepts: making decisions under uncertainty and modeling the real world. This is all about making assumptions– here are some definitions:

  • Frequentist: $y$ (data) is random, $\theta$ (parameter) is fixed
  • Bayesian: $y$ is random, $\theta$ is random
  • Parametric: Make assumptions about the relationship between $\theta$ and $y$, then use these assumptions to find the best value of $\theta$ given $y$
  • Nonparametric: Don’t make any assumptions, and find any good function $f$ such that $\theta = f(y)$

For the most part, these notes should be pretty complete in terms of content, but could use some cleaning up (as well as more examples).
