报告内容简介Factor models have been widely applied in economics and finance, and the well-known heavy-tailedness of macroeconomic/financial data should be taken into account. In this talk, I will introduce the existing robust factor analysis methods, namely, the Huber Principal Component Analysis (HPCA), the Quantile Factor Analysis (QFA) and the Robust Two Step (RTS). In recent years, matrix-valued or even high order tensor time series have been common in areas of economics and finance. I will also introduce the existing robust factor analysis tools for well-structured matrix/tensor data, extending the HPCA, QFA and RTS in a proper way. The talk is based on some recent work by our group and we also develop an R package “HDRFA” which is available at CRAN https://cran.r-project.org/web/packages/HDRFA/index.html, and related papers are available at my personal website https://heyongstat.github.io/.
