Abstract

Gross domestic product (GDP) serves as a vital indicator of a country’s economic health, influenced by factors such as unemployment rates, export-import dynamics, and inflation rates. Understanding the intricate relationship between GDP and unemployment is crucial for navigating the dynamic business environment. This study investigates this relationship in Somalia using both frequentist and Bayesian regression approaches. The frequentist approach, particularly ordinary least squares, is chosen for its widespread use and simplicity in estimating parameters by minimizing the sum of squared deviations. Meanwhile, the Bayesian approach is adopted for its flexibility in integrating prior information and updating estimates as new data emerge, providing a probabilistic framework that accommodates parameter uncertainty. Secondary data from the World Bank spanning 1991–2020 were analyzed. The results reveal a significant negative association between unemployment and GDP in both models. Comparative analysis employing mean absolute error, root mean square error, and mean square error indicates comparable predictive accuracy between the two approaches, with the Bayesian model demonstrating slight advantages. Bayesian convergence diagnostics affirm satisfactory model stability. These findings offer valuable insights for policymakers, aiding in the formulation of strategies to address unemployment challenges and stimulate economic growth in Somalia.The study investigates the relationship between unemployment and GDP in Somalia, employing both frequentist and Bayesian statistical methods. The frequentist approach provides point estimates and confidence intervals based on observed data, while the Bayesian approach incorporates prior knowledge and uncertainty into the analysis, yielding posterior distributions. By comparing these methods, the research aims to provide a comprehensive understanding of how GDP influences unemployment rates and vice versa. The results highlight the strengths and limitations of each approach, offering valuable insights for economic policymakers and contributing to the broader field of economic analysis in developing countries.
