Determining the optimal window size for longitudinal network analysis is challenging. This study introduces a novel approach using actor-level dynamicity to find the correct window size for various network perspectives.

Area of Science:

  • Network Science
  • Data Analysis
  • Computational Social Science

Background:

  • Longitudinal network analysis requires selecting an appropriate time window size.
  • Existing methods lack a comprehensive solution applicable to diverse longitudinal networks.
  • Actor-level perspectives, like centrality and participation, are crucial for temporal network analysis.

Purpose of the Study:

  • To propose a novel approach for determining the optimal window size in longitudinal network analysis.
  • To address the challenge of selecting appropriate window sizes for various actor-level perspectives.
  • To provide a generalizable solution for different types of longitudinal networks.

Main Methods:

  • Introducing the concept of actor-level dynamicity to quantify behavioral variability.
