How to Detect Network Dependence in Latent Factor Models? A Bias-Corrected CD Test
潜在因子模型中的网络依赖检测:偏误修正 CD 检验
In a recent paper Juodis and Reese (2022) (JR) show that the application of the CD test proposed by Pesaran (2004) to residuals from panels with latent factors results in over-rejection. They propose a randomized test statistic to correct for over-rejection, and add a screening component to achieve power. This paper considers the same problem but from a different perspective, and shows that the standard CD test remains valid if the latent factors are weak in the sense the…
