Fig. 5From: Infestation risk of the intermediate snail host of Schistosoma japonicum in the Yangtze River Basin: improved results by spatial reassessment and a random forest approachVariable importance and model calibration of random forest at 5Â km spatial re-assessment. a The ranks of contribution by all variables to the occurrence probability of snail infestation. b Calibration of model prediction in the training set, with a good fitness with the real observed snail infestation probability as the response and the predicted snail infestation probability as the predictor variableBack to article page
