This study introduces an improved EM algorithm for the mover-stayer model, enhancing analysis of population changes over time. The method also addresses incomplete data in panel studies, improving mobility research.

Area of Science:

  • Social Sciences
  • Statistics
  • Epidemiology

Background:

  • The mover-stayer model analyzes population dynamics over time.
  • Heterogeneous populations present unique challenges in longitudinal studies.
  • Existing methods may not fully address data complexities like incomplete follow-up.

Purpose of the Study:

  • To present an alternative method for estimating mover-stayer model parameters using the EM algorithm.
  • To extend the mover-stayer model for handling incomplete follow-up data in panel studies.
  • To illustrate the application of these models and methods with real-world survey data.

Main Methods:

  • Application of the Expectation-Maximization (EM) algorithm for parameter estimation.
  • Development of an extended mover-stayer model to accommodate missing data.
