Survival Analysis for the Evolution of Lifespan of Electrical and Electronic Equipment: A Case Study of Television Equipment in Peru

This research presents a framework for analyzing the life cycle evolution of first use of electronic and electrical devices for the assessment and management of Waste Electrical and Electronic Equipment (WEEE), with a focus on television equipment in Peru as a case study. This analysis is based on data from official entities such as National Institute of Statistics and Informatics (Instituto Nacional de Estadística e Informática or INEI), providing a basis for research. The study begins with the application of non-parametric methods, such as the Kaplan-Meier method, to estimate the lifespan of televisions, followed by an analysis using parametric models that suit the nature of the data, implementing statistical validation techniques to ensure the reliability of the obtained results. The proposed framework highlights retention and management patterns of the electrical devices in the examined context and offers a structure for similar studies in different contexts or regions. By focusing on official data sources, the study proposes a methodology, paving the way for policy formulation for the management of waste from electrical and electronic equipment.
