We will review working with expectation operators and matrix algebra. We will study various statistical models utlizied to test theoretical economic relationships, analyze historical economic events, and conduct economic policy evaluation. Simple and multiple regression using ordinary least squares estimation, maximum likelihood estimation, and general;ized least squares estimation will be covered in detail. We will learn tools of basic statistical inference and diagnostics for these models. Time-allowing, we will study logit and probit regressions to handle discrete choices (e.g. Yes/No choice scenarios). basic time-series analyses with tests and controls for trends, seasonality, and auto correlation.
