SAM1A, SAM2, and MET2 should be completed no later than the semester before the student begins SAM4A.
Parts of MET4 are relevant for SAM4A. Ideally, MET4 should be taken before or concurrently with SAM4A.
In particular, this includes microeconomics (theory of consumer behavior, theory of producer behavior, and market theory), statistics for economists (probability theory, conditional probability, random variables, mean and variance, joint distributions, common probability distributions, estimation and estimators, hypothesis testing, linear regression in one and several variables), and empirical methods (writing scripts in R, interpretation of economic and behavioral data).
