Applied Statistics Seminar by Prof. Minh-Ngoc Tran, University of Sydney Wed, 12 Jul 2023 20:17:27 +0000 Read More]]> Title: Statistics in the data-centric era

Invited Speaker: Professor Minh-Ngoc Tran, Business School, University of Sydney, Australia.

Time: 2PM, Wednesday July 19, 2023.

Location: Room A2. 501, International University, VNU-HCM.

Abstract: Statistics has demonstrated it is escalating significance in the data-centric era, manifesting itself as both a specialized academic discipline and an interdisciplinary field. In this presentation, I aim to provide a birds-eye overview of Bayesian statistics and shed light on its recent advancements. I will then delve into two specific statistical applications that have occupied my attention over the past few years: financial econometrics and empirical psychology. Throughout the discussion, I will recount my personal experiences collaborating with psychologists and financial econometricians as a statistician, emphasizing the invaluable insights gained from these interactions.

Econometrics and Applied Statistics Seminar by Professor Michael Wolf, University of Zurich Wed, 07 Sep 2022 09:50:37 +0000 Read More]]> Seminar title: Large dynamic covariance matrices: Enhancements based on intraday data

Invited Speaker: Professor Michael Wolf, University of Zurich, Switzerland.

Time and date: 2:00 PM, Wednesday, 14 September 2022.

Location: Room A1.204, International University, Vietnam National University-HCM, Quarter 6, Linh Trung Ward, Thu Duc City, Ho Chi Minh City.


Multivariate GARCH models do not perform well in large dimensions due to the so-called curse of dimensionality. The recent DCC-NL model of Engle et al. (2019) is able to overcome this curse via nonlinear shrinkage estimation of the unconditional correlation matrix. In this paper, we show how performance can be increased further by using open/high/low/close (OHLC) price data instead of simply using daily returns. A key innovation, for the improved modeling of not only dynamic variances but also of dynamic correlations, is the concept of a regularized return, obtained from a volatility proxy in conjunction with a smoothed sign of the observed return.

About the speaker:     

Michael Wolf is a Professor of Econometrics and Applied Statistics at the University of Zurich and holds a Ph.D. in Statistics from Stanford University. Before joining the Department of Economics at the University of Zurich, he held previous positions at The University of California (Los Angeles), Universidad Carlos III (Madrid), and Universitat Pompeu Fabra (Barcelona). Michael Wolf’s research interests include resampling-based inference, multiple testing methods, the estimation of large-dimensional covariance matrices, and financial econometrics.  His research has been published in leading journals, such as The Annals of Statistics, Biometrika, Econometrica, Journal of the American Statistical Association, and The Review of Financial Studies.

Webinar: Differential Game Models Of Optimal Debt Management by Prof. Khai Nguyen, NCSU Tue, 07 Jun 2022 14:54:07 +0000 Read More]]> Title: Differential Game Models Of Optimal Debt Management

Speaker: Dr. Nguyễn Tiến Khải, Associate Professor, Department of Mathematics, North Carolina State University

Time: 9 AM, Sunday – 12 June 2022. Via Zoom. Meeting ID: 215 811 8519. Passcode: 879771

Abstract: I will present recent results on the game-theoretical formulation of optimal debt management problems in an infinite time horizon with exponential discount, modeled as a non-cooperative interaction between a borrower and a pool of risk-neutral lenders. Here, the yearly income of the borrower is governed by a stochastic process and bankruptcy instantly occurs when the debt-to-income ratio reaches a threshold. Since the borrower may go bankrupt in finite time, the risk-neutral lenders will charge a higher interest rate in order to compensate for this possible loss of their investment. Thus, a “solution” must be understood as a Nash equilibrium, where the strategy implemented by the borrower represents the best reply to the strategy adopted by the lenders, and conversely. This leads to highly nonstandard optimization processes”.
