Bias Correction in Factor-Augmented Regression Models with Weak Factors

Peiyun Jiang, Yoshimasa Uematsu, Takashi Yamagata

In this paper, we study the asymptotic bias of the factor-augmented regression estimator and its reduction, which is augmented by the factors extracted from a large number of $…

Revisiting Asymptotic Theory for Principal Component Estimators of Approximate Factor Models

Peiyun Jiang, Yoshimasa Uematsu, Takashi Yamagata

It is well known that approximate factor models exhibit rotation indeterminacy. Principal component (PC) estimators are typically analyzed relative to a rotated factor-loading repr…

Moment-Based Adjustments of Statistical Inference in High-Dimensional Generalized Linear Models

Kazuma Sawaya, Yoshimasa Uematsu, Masaaki Imaizumi

We develop a statistical inference method for generalized linear models (GLMs) in high-dimensional settings, where the number of unknown coefficients is of the same order as th…
