Determinants of Smallholder Rubber Yield in Southern Nigeria: Empirical Evidence from OLS, Ridge, Lasso, PCR and PLS Models
Natural rubber production remains important to smallholder agriculture in Southern Nigeria, but yields are constrained by suboptimal input use and correlated production factors. This study examined determinants of rubber yield using farm-level data from 200 farms across three Nigerian states for 2021–2025, obtained fro...
