Revealing Cluster Structures Based on Mixed Sampling Frequencies
share
This paper proposes a new nonparametric mixed data sampling (MIDAS) model and develops a framework to infer clusters in a panel dataset of mixed sampling frequencies. The nonparametric MIDAS estimation method is more flexible but substantially less costly to estimate than existing approaches. The proposed clustering algorithm successfully recovers true membership in the cross-section both in theory and in simulations without requiring prior knowledge such as the number of clusters. This methodology is applied to estimate a mixed-frequency Okun's law model for the state-level data in the U.S. and uncovers four clusters based on the dynamic features of labor markets.
