Morris screening is simple to implement and does not require extensive computations. Implementation of Morris method is available in the supplemental material. Two metrics will be available from Morris method to assist parameter ranking, i.e, mean μ or μ* and standard deviation σ. A high μ or μ* indicates a parameter with an important overall influence on the model outputs; a high σ indicates either a parameter interacting with other factors or that its effect is non-linear. The magnitudes of μ and σ for each model parameter are relative to the others (12). Although they are not that informative, they still show some information about rate of changes.
