Sensitivity Analysis and How Nature Fights Back

Sensitivity analysis is still very popular, especially in engineering design. The idea is simple. Suppose you have a function of three variables, f(x, y, z). This is how it works: 1) you freeze all your design variables except one; 2) you perturb the variable which is loose; 3) you measure how the performance of the system varies as the loose design variable is perturbed. What could be wrong…
