Data: Probability Distributions & Inference
- We need probability distributions for stat. inference (learning from sample about the population)
- Frequentism/Frequentist inference
- Any given experiment (dataset) can be considered as one of an infinite sequence of possible repetitions of the same experiment (datasets)
- Sample of students in class = one of infinite sequences of sample we could draw from Mannheim Univ. students
- Sample → Calculate mean/regression coefficient → Sampling distribution of statistic \(\approx\) probability distribution
- Bayesian inference
