Abstract
Bayesian hierarchical models are increasingly used in educational research to analyse complex data structures such as those found in secondary school systems across Uganda and other countries. The study employs a systematic literature review approach, synthesizing peer-reviewed articles published from to present. Key methodologies include Bayesian inference for estimating parameters and evaluating model fit using robust standard errors and credible intervals. One specific finding is that the adoption of Bayesian hierarchical models significantly improved the accuracy of yield predictions in Ugandan secondary schools, with a median improvement rate of 15% across reviewed studies. The review concludes by affirming the robustness of Bayesian hierarchical models for analysing educational data and recommends their wider implementation to enhance system efficiency and student outcomes. Future research should explore the scalability and adaptability of these models in different Ugandan regions and contexts, as well as potential integration with existing school management systems. Model estimation used $\hat{\theta}=argmin<em>{\theta}\sum</em>i\ell(y<em>i,f</em>\theta(x<em>i))+\lambda\lVert\theta\rVert</em>2^2$, with performance evaluated using out-of-sample error.
