Methodological Evaluation of Regional Monitoring Networks Systems in Nigeria Using Bayesian Hierarchical Models for Cost-Effectiveness Analysis

Regional monitoring networks in Nigeria have been established to improve data collection and analysis for policy-making. A systematic literature review will be conducted, focusing on methodologies used in Nigerian monitoring networks. Bayesian hierarchical models will be employed to assess cost-effectiveness. Bayesian hierarchical models revealed significant variability in the cost-effectiveness of different network configurations across regions. The application of Bayesian hierarchical models provides a robust framework for evaluating and comparing regional monitoring systems' performance and costs. Future research should consider implementing these models to guide resource allocation within Nigerian monitoring networks. Model estimation used θ̂=argminθ∑ᵢ(yᵢ,f_θ(xᵢ))+λθ₂², with performance evaluated using out-of-sample error.
