Type II sensitivity occurs when vanation of an mput causes significant changes m the residuals but insignificant changes in the model’s conclusions. Tkype II sensitivity is of no concern because, regardless of the value of the input, the conclusion will remain the same.

Type III sensitivity occurs when variation of an input causes significant changes to both the residuals and the model’s conclusions. Type III sensitivity is of no concern because, even though the model’s conclusions change as a result of variation of the input, the parameters used in those simulations cause the model to become uncalibrated.

Type IV sensitivity occurs when variation of an input causes in the residuals but significant changes in the model’s conclusions. Type IV sensitivity can invalidate model results because, over the rangę of the that parameter in which the model can be considered calibradted, the conclusions of the model can change significantly.
