Line 19:
Each trajectory is composed of <math>(k+1)</math> points since input factors move one by one of a step <math> \Delta </math> in <math>\{0, 1/(p-1), ... , 1-1/(p-1), 1\}</math> while all the others remain fixed.
 
Along each trajectory the so -called ''elementary effect'' for each input factor is defined as:
 
: <math> d_i(X) = \frac{Y(X_1, \ldots ,X_{i-1}, X_i + \Delta, X_{i+1}, \ldots, X_k ) - Y( \mathbf X)}{\Delta} </math>,
