Comparing distress caused by CCl₄ injections or bile duct ligation using SVM classification. In both plots green and red squares indicate distress level 0 or distress level 1 of the BDL training data set and crosses denote data classified as distress level 0, whereas circled crosses denote data classified as distress level 1. Blue crosses denote post-CCl₄ (a) and post-BDL (b) distress. A 2 × 2 contingency table compares the distributions of predicted distress levels of post-CCl₄ to the post-BDL test data set (c). A significantly different distribution of distress levels between these data sets has been determined by Fisher’s Exact Test, *P ≤ 0.001), CCl₄: n = 30 data points; BDL: n = 15 data points.
