# {{Sensi}} module

The **{{Sensi}}** library (cf [](#sensitivity_module)) allows to perform sensitivity analysis of one 
of the output response $Y$ with respect to the input factors $X_i$ (for $i=1,\hdots,n_X$). The very 
basic concepts of sensitivity analysis are introduced as well in the introduction of this chapter 
while they are discussed a bit more thoroughly in {{metho}}.
