Statistics Seminar - 04/11/23

Abstract:

As the US Census Bureau aims to increase the frequency of data dissemination, the topic of signal extraction has gained significant attention. This talk will delve into multiple research threads related to the challenges of performing signal extraction. Specifically, we introduce a class of difference stationary latent component models that can be used to identify structural components. Within this class, we will explore two open areas of research: multivariate extraction and fractional periodicities. These areas each present unique challenges. To illustrate the practical applications of this methodology, we will present case studies involving daily immigration and weekly business formation statistics.
