Course-note compilation for Columbia's summer real analysis course — nine chapters of lecture notes, problem sets with worked solutions, and a curated bibliography, tracking Rudin's Principles of Mathematical Analysis.
A workshop for students who want to work on forecasting and nowcasting. Eight sessions, each pairing one method with the code that runs it on real data, from the Kalman filter to a live GDP dashboard — with notes, slides, browser-based explorables, five practica, and a capstone scored against the Fed's own nowcasts.
My notes and MATLAB replications from BSE's macroeconometrics course, with worked exercises for all ten sessions. The material covers VARs, local projections, nonlinear models, and factor methods.
