Notes

The importance factors \alpha_i are evaluated from the coordinates of the mean point of event domain \vect{X}^*_{event}, mapped into the standard space as follows:

\alpha_i = \displaystyle \frac{\left(U_{i}^*\right)^2}{||\vect{U}^*||^2}

where \vect{U}^* = T(\vect{X}^*_{event}) with T the iso-probabilistic transformation and the mean point \vect{X}^*_{event} = \displaystyle \frac{1}{n} \sum_{i=1}^{n} \vect{X}_i 1_{event}(\vect{X}_i).

Warning

This notion is only available if the history mecanism of the model is activated (see MemoizeFunction).
