Biography

Welcome to Young Geun Kim’s long-range dependent academic path! Young-geun Kim is a Ph.D. candidate in statistics at Sungkyunkwan University (SKKU). His research interest mainly begins with a time series. It includes high-dimensional time series, long-range dependency, Bayesian VAR modeling, et cetera. He is developing forecasting models based on Bayesian VAR having Minnesota prior and various shrinkage priors.

Interests
  • Long-range dependence
  • Vector autoregression (VAR)
  • Heterogeneous autoregression (HAR)
  • Bayesian econometrics
  • Anomaly detection
  • and more 🤔
Education

  • Ph.D., 2025 (expected)

    Sungkyunkwan University, Seoul, Korea

  • BEc in Statistics, 2019

    Sungkyunkwan University, Seoul, Korea
