3.12 Data: Probability Distributions

  • Sometimes called theoretical distributions (as opposed to empirical)
  • Invented by mathematicians/statisticians
    • Q: What is the most famous one? Who invented it? Others?
  • Discrete and continuous probability distributions
  • Uni- and multivariate probability distributions
  • Q: Facilitate our work… why? What assumptions can we make?
  • When we draw from a probability distribution we also simply generate (artificial) data
    • R: rbinom(10, 1, 0.2) = 0, 0, 0, 0, 0, 0, 0, 0, 1, 1
