Explanatory variables ranked as the most-to-least important by CART are as follows: week, type of melon, year, size, grade, and shipping container. The most notable price change occurs when prices fall after 13 May.https://ageconsearch.umn.edu/record/30924binary splitcarthedonicrelative importanceterminal node
