Introduction and Application of the Multiple Event Process Survival Mixture Model

The purpose of this study is to introduce and apply the Multiple Event Process Survival Mixture (MEPSUM) model, a method for identifying latent classes by considering the occurrence and timing of various events, and to apply it to real data. To this end, survival analysis and mixture models for a single event were explained, followed by an introduction to survival mixture models that combine the two. Furthermore, MEPSUM, which is designed to analyze multiple events, was introduced with a focus on its fundamental concepts, considerations for analysis, data suitability, and examples from prior studies to aid understanding. Subsequently, the study applied MEPSUM to real data from the Seoul Education Longitudinal Study to analyze the initial risk of various school violence perpetration behaviors (e.g., bullying, physical violence, rumor spreading, extortion, and threats) from 6th grade to 12th grade. By introducing a method for simultaneously considering and categorizing the occurrence of multiple events and presenting analytical results using actual data, this study aims to contribute to research on the occurrence of educational and social events.
