Lecture 6: Stochastic Processes I (cont.); Regression Analysis

MIT 18.642 Topics in Mathematics with Applications in Finance, Fall 2024 Instructor: Peter Kempthorne View the complete course: https://ocw.mit.edu/courses/18-642-topics-in-mathematics-with-applications-in-finance-fall-2024 YouTube Playlist: https://www.youtube.com/playlist?list=PLUl4u3cNGP601Q2jo-J_3raNCMMs6Jves The lecture discusses martingales and their powerful applications in solving problems in stochastic processes, including random walks, stopping times, and gambler’s ruin probabilities, highlighting how martingale properties simplify complex analyses. It then introduces Markov processes and chains, explaining their memoryless property and applications in finance such as credit rating transitions and stock price modeling, before transitioning to regression analysis, focusing on multiple linear regression, model assumptions, and estimation techniques.
