To support evidence-based policy and research, this paper proposes a hybrid machine learning approach combining least squares and support vector machine (LS-SVM) to improve robust prediction. Using UNESCO-compiled global out-of-school datasets from 1975–2020, the method is evaluated against standard SVM using NRMSE and MAPE. Results show LS-SVM achieves lower error and stronger precision, providing guidance for effective global trend assessment and forecasting.","Statistical and Machine Learning Approach for Robust Assessment Modelling of Out-of-School Children Rate: Global Perspective  \nEdith Edimo Joseph*  \nDepartment of Educational Psychology, University of KwaZulu-Natal, Edgewood Campus, South Africa  \nE-mail: [edimo8383@gmail.com](edimo8383@gmail.com)  \nORCID iD: [https://orcid.org/0000-0001-6148-9127](https://orcid.org/0000-0001-6148-9127)  \n*Corresponding Author  \nJoseph Isabona  \nDepartment of Physics, Federal University Lokoja, Lokoja, Kogi State, Nigeria E-mail: [joseph.isabona@fulokoja.edu.ng](joseph.isabona@fulokoja.edu.ng)  \nORCID iD: [https://orcid.org/0000-0002-2606-4315](https://orcid.org/0000-0002-2606-4315)  \nSunday Dare  \nDepartment of Educational Psychology, University of KwaZulu-Natal, Edgewood Campus, South Africa  \nE-mail: [adesojisunday@gmail.com](adesojisunday@gmail.com)  \nOdaro Osayande  \nCentre for Learning Resources, Covenant University, Ota, Ogun State, Nigeria E-mail: [odaro.osayande@covenantuniversity.edu.ng](odaro.osayande@covenantuniversity.edu.ng)  \nORCID iD: [https://orcid.org/0000-0002-5771-9548](https://orcid.org/0000-0002-5771-9548)  \nOkiemute Roberts Omasheye  \nDelta State College of Education, Mosogar, Nigeria  \nE-mail: [okiemuteomasheye@yahoo.com](okiemuteomasheye@yahoo.com)  \nReceived: 14 November 2022; Revised: 04 January 2023; Accepted: 11 March 2023; Published: 08 June 2023  \nAbstract: The negative impact of out-of-school students' problems at the basic and high-school levels is always very weighty on the affected individuals, parents, and society at large. Owing to the weighty negative consequences, policymakers, different government agencies, educators and researchers have long been looking for how to effectively study and forecast the trends as a means of offering a concrete solution to the problem. This paper develops a better hybrid machine learning method, which combines the least square and support vector machine (LS-SVM) model for robust prediction improvement of out-of-school children trend patterns. Particularly, while other previous works only engaged some regional and few samples of out-of-school datasets, this paper focused on long-ranged global out-of-school datasets, collated by UNESCO between 1975-2020. The proposed hybrid method exhibits the optimal precision accuracies with the LS-SVM model in comparison with ones made using the ordinary SVM model. The precision performance of both LS-SVM and SVM was quantified and a lower NRMSE value is preferred. From the results, the LS-SVM attained lower error values of 0.0164, 0.0221, 0.0268, 0.0209, 0.0158, 0.0201, 0.0147 and 0.0095 0.0188, compared to the SVM model that attained higher NRMSE values of 0.041, ,0.0628, 0.0381, 0.0490, 0.0501, 0.0493, 0.0514, 0.0617 and 0.0646, respectively. By engaging the MAPE indicator, which expresses the mean disconnection between the sourced and predicted values of the out-of-school data. By means of the MAPE, LS-SVM attained lower error values of 0.51, 1.88, 0.82, 2.38, 0.62, 2.55, 0.60, 0.60, 1.63 while SVM attained 1.83, 7.39, 1.79 7.01, 2.43, 8.79, 2.58, 4.13, 6.18. This implies that the LS-SVM model has better precision performance than the SVM model. The results attained in this work can serve as an excellent guide on how to explore hybrid machine-learning techniques to effectively study and predict out-of-school students among researchers and educators.  \nIndex Terms: Global Perspective, LS-SVM, Out-of-School Children, SVM, UNESCO.  \n1. Introduction  \nProper education remained a better means of boosting individual well-being, fighting poverty, combating crime, reducing social vices, fostering peace, strengthening egalitarianism, sustaining the environment, and ensuring gender parity in society.
