From: Using random forests to model 90-day hometime in people with stroke
Two-way partial dependence plots depicting the relationship between frailty, age, and predicted 90-day hometime. The top two plots depict this relationship in a three-dimensional plot viewed from two different perspectives with predicted hometime displayed on the z-axis. The bottom plot displays this relationship using a two-dimensional contour plot. All three plots use the same color scale to represent predicted 90-day hometime where darker colors indicate less hometime. Frailty scores range from 0 to 99 with higher scores indicating greater risk of frailty (scores < 5 indicate low risk of frailty, scores 5–15 indicate moderate risk of frailty and scores > 15 indicate high risk of frailty) [18]
