Adaptive Strategy of Testing Alphas in High Dimensional Linear Factor Pricing Models
Published 10 Apr 2024 in stat.ME | (2404.06984v1)
Abstract: In recent years, there has been considerable research on testing alphas in high-dimensional linear factor pricing models. In our study, we introduce a novel max-type test procedure that performs well under sparse alternatives. Furthermore, we demonstrate that this new max-type test procedure is asymptotically independent from the sum-type test procedure proposed by Pesaran and Yamagata (2017). Building on this, we propose a Fisher combination test procedure that exhibits good performance for both dense and sparse alternatives.
