Below are misc. documents for applied econometrics research, that I update regularly. (Originally personal notes, then used as foundation for teaching PhD students, now put online in case they can be useful to others.)

Applied statistics

• Probability distributions in regression modeling
  The essential statistics definitions & theorems (esp. LLN & CLT) that make the statistics below work.

• Microeconometrics within Inferential Statistics
  Basic inferential statistics most commonly used in applied microeconometrics. Models as probability distributions; inference workflow …

• Causal inference in observational studies, Theory & Methods
  Using regression to uncover the causal effect of a treatment on a population.
  1. Underlying theoretical framework: potential outcomes
  2. Applied methods (RDD, IV…); equivalence of the regression slope estimate in terms of potential outcomes
  3. Improving inferences (matching & controls, falsification tests, randomization inference…)
• Assumptions of the classical linear regression model (and what to do when they fail)
  1. Typical assumptions
  2. What do they provide? (Estimator properties)
  3. What to do when they are violated?

Data wrangling

• Wrangling spatial data in R
