Calculates exchangeable shock-size-arrival intensities, the
ex_intensities parameter for rexmo().
Arguments
- object
An object deriving from the class BernsteinFunction.
- d
A positive integer, larger than two, for the dimension.
- cscale
A positive number for the composite scaling factor.
- ...
pass-through parameter.
Details
For a given Bernstein function, the exchangeable shock-size-arrival intensities are defined as $$ \eta_{i} = \binom{d}{i} {(-1)}^{i-1} \Delta^{i}{ \psi{(d-i)} } , \quad 1 \leq i \leq d . $$ The calculation of the exchangeable shock-size-arrival intensities using this formula is usually not numerically stable. Consequently, the various alternative approaches are used dependent on the class of the Bernstein function.
