where PV Ai, Δ, g stands for the present value of asset i under the scenario Δ corresponding to simulation g. In contrast, PV Ai indicates the present value of the same asset under x0. In more detail, the present value of each asset Ai under the current (t0) economic conditions is...
the model trained at each time step was then tested at all the time steps on the testing set trials, at each cross-validation fold. The classifier performance at each training and testing time was evaluated by the area under the receiver operating curve (AUC) at each cross-validation fold....
We normalized the reverse correlation curve to have an area under the curve equal to one. This step lets the curves be interpreted in units of effective weight at each time point. A flat reverse correlation curve indicates even weighting of evidence across all time points. Previous studies in ...
