Advanced Econometrics 2

Graduate course, GSEFM, Goethe University Frankfurt, 2019

This part of the course, part of the first-year MSQ/Ph.D. Program course sequence at GSEFM, will examine single- and multiple-equation modeling in time series and panels, with a specific focus on so-called autoregressive distributed lag models, vector autoregressions and vector error correction models.

Financial Econometrics

Undergraduate course, ISEM, Capital University of Econimcs and Business, 2019

The course introduces students to econometric methods applied in fiancial economics. In particular, this course focuses on the estimation and inferential methods used in empirical analysis of modern finance theory. Due to the applied emphasis, classes will cover MATLAB and Stata programming to implement the tools discussed in the lectures as well.

Applied Stochastic Process

Undergraduate course, ISEM, Capital University of Econimcs and Business, 2020

This course introduces the theory and applications of several important stochastic processes. The course mainly includes Markov chains, Poisson process and Brownian motion. Students can also understand how to solve complicated problems using Monte Carlo simulation.

Applied Stochastic Process (Part 2)

Undergraduate course, ISEM, Capital University of Econimcs and Business, 2021

This course introduces the theory and applications of several important stochastic processes. The course mainly includes Markov chains, Poisson process and Brownian motion.

Financial Modelling and Data Analysis (Part 2)

Undergraduate course, ISEM, Capital University of Econimcs and Business, 2022

This course introduces some basic modeling skills for analyzing financial data like equity returns. It will provide a foundation of basic theory and methodology as well as applied examples with essential statistical and computational techniques to analyzing financial data.
