VaR_Spec__Modelled_Factor__ShiftGiven a simulated value x of the referenced risk factor at time t, the corresponding numerical value m(x;t) of the affected market element bucket (eg a single deposit rate or vol) is given by the sum:
m(x;t) = m(0) + x, where m(0) is the initial known value of this market element bucket.
Effectively this amounts to defining the risk factor as the random difference m(t) - m(0), rather than m(t) itself.
Although not required, this setting is usually accompaqnied by a VaR Spec::Process Type setting of VaR Spec::Process Type::Normal
