BorderEffect: Detection of Edge Effects in Field Trials via Besag-Kempton Competition

Estimates and evaluates the intraspecific competition coefficient associated with the edge (border) effect in agricultural field trials, using the Besag-Kempton autoregressive model and a least-squares estimator following Darghan, Rivera, Gonzalez and Castellanos (2022) <doi:10.47280/RevFacAgron(LUZ).v39.n1.18>. Provides field-layout generation, spatial weight matrices, a formula interface for arbitrary two-way designs, a simulation-based decision procedure for presence or absence of the edge effect, Moran's I diagnostics, and a 'shiny' application.
