Table 3 Characteristics of the predictors in the NPMR models reported in this study for the building (n = 1444) and validation (n = 364) sets. Note that the validation step used the tolerance of the predictors from the building step, while the sensitivity was computed for each model

  1. aTolerance is the span covered by one standard deviation of the Gaussian weighting function, reported in the original scale of the predictor
  2. bFor comparison among predictors, tolerance is also divided by the range of the predictor and expressed as a percentage
  3. cSensitivity is the mean absolute difference resulting from nudging the predictors, expressed as a proportion of the range of the response variable
