From: An interaction regression model for crop yield prediction
The circular graphs show that interactions for corn (left) and soybean (right) that were discovered by the proposed model. Curves inside the inner circle connect the two variables involved in the interactions. The first layer outside the circle shows the positive (red) or negative (blue) effects of the interactions. These plots were created with MATLAB R2018a (Version 9.4.0.813654 64-bit).
