## Sensitivity Analysis

That is, quantifying the influence of an input on the output.

When an estimator says that some factor is not worth consideration ("it's pennies")
it is usually meant that the estimate is not especially **sensitive** to that factor.

[[sensitivity|Sensitivity]], I think, is a much quicker concept to grasp
than [[value-of-information|the value of information]],
even if VOI can explain the same motivations and more completely.
