Special Issue Information

Dear Colleagues,

Due to recent advancements in the fields of artificial intelligence and machine learning, massive amounts of data have been collected via various channels under different formats. While the growing availability of information would generally lead to significant scientific progression, it also presents great challenges in adequately analyzing such massive datasets. To this end, the scientific literature over various topics of computational statistics and data science have significantly grown in recent years. The following topics have gained increasing attentions:  dimension reduction, feature screening, variable selection, optimal sampling, multitask learning, transfer learning, and distributed learning, among others. In this Special Issue, entitled “Methodology and Application in Computational Statistics and Data Science”, we invite papers to address both the methodological and computational aspects of dealing with challenges in the analysis of large datasets and new data types, including functional data, big data, network data, and others. We also welcome papers that specifically focus on applying the latest methods to the analysis of challenging datasets with complex structures, such as in the areas of biostatistics, genetics, spatial statistics, and others.

This study evaluates the limitations of gravity models in constructing regional association networks, using China’s interprovincial economic connections as a case study. Comparison between a gravity-model-based simulated network and an actual network reveals significant topological differences. The gravity model overestimates the influence of larger, inward-oriented provinces and fails to accurately represent external connections. Attempts to refine the model with additional variables proved ineffective. Further theoretical analysis attributes these deficiencies to measurement bias from the model’s simplified binary perspective and information loss due to dimensional mismatch between pairwise predictions and complex network structures. These findings underscore the need for cautious application of gravity models and the development of more comprehensive analytical frameworks in regional network analysis. Full article
