VeraCrop: Yield Gap Analysis Using Comparative Performance Analysis
Implements automated variable-type detection, preprocessing,
encoding, scaling, model diagnostics, variable selection, and yield gap
computation for agricultural comparative performance analysis (CPA).
The comparative performance analysis approach is described in de Bie
(2004) <doi:10.1016/j.scienta.2003.11.017>. For an overview of yield
gap assessment methodologies, see Kamkar et al. (2025)
<doi:10.1016/j.agsy.2025.104392>.
