ZDD - [YpE] Generalized Laplace (High Overload Shapes)

This is the Zero Distortion Density (ZDD) used in the GenHVL[YpE] models.

The [YpE] model is used only for preparative (extremely high overload) shapes. The starting estimates for the [YpE] density assume such shapes.

This model's a1 center parameter is the mode of the underlying double-sided exponential. The a3 parameter in the ZDD nomenclature below adjusts the asymmetry, and thus the third moment or skew of the peak.

There is no GenNLC[YpE] model.
