Partial Independence Plots

  • Plot how prediction / output changes with changes in one input
  • Assuming other variables held constant (typically at average for the dataset)
  • Can show marginal effects or key thresholds as the value of the input changes
  • Need to be aware that assuming other variables don’t change may not be realistic -
    • inputs may be correlated
