Estimating site-specific crop yield response to changes input (e.g., seed, fertilizer) management is a critical step in making economically optimal recommendations. Past studies have attempted estimate functions using various Machine Learning (ML) methods, including the Random Forest (RF), Boosted (BRF), and Convolutional Neural Network (CNN) methods. This study proposes use of Causal (CF) mode...
