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
- e.g. multivariate normal: What is the 3rd dimension?
- 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
- R:
