Attribute Selection Impact on Linear and Nonlinear Regression Models for Crop Yield Prediction

Table 4

Attributes in OAS and LAS selected by each crop technique. Attributes in optimal subset (OAS) are remarked with asterisks. Attributes selected with training data (LAS) are identified with the √ symbol.
