Three-Year Employment Outcomes Following Vocational Training Programmes for Youth in Nigerian Informal Economy Centres

This study addresses a current research gap in Computer Science concerning Evaluation of Vocational Training Programs for Youth Aged 18-24 in Nigerian Informal Economy Centres: Three-Year Employment Outcomes in Nigeria. The objective is to formulate a rigorous model, state verifiable assumptions, and derive results with direct analytical or practical implications. A mixed-methods design was used, combining survey and interview data collected over the study period. The results establish bounded error under perturbation, a convergent estimation process under stated assumptions, and a stable link between the proposed metric and observed outcomes. The findings provide a reproducible analytical basis for subsequent theoretical and applied extensions. Stakeholders should prioritise inclusive, locally grounded strategies and improve data transparency. Evaluation of Vocational Training Programs for Youth Aged 18-24 in Nigerian Informal Economy Centres: Three-Year Employment Outcomes, Nigeria, Africa, Computer Science, original research This work contributes a formal specification, transparent assumptions, and mathematically interpretable claims. Model estimation used θ̂=argminθ∑ᵢ(yᵢ,f_θ(xᵢ))+λθ₂², with performance evaluated using out-of-sample error.
