ZDD - [E] Exponentially-Modified Gaussian (EMG)

This is the Zero
Distortion Density (ZDD) used in the GenHVL[E] models. This EMG a_{1} center parameter is
the mean of the underlying Gaussian. The a_{3} parameter in the ZDD nomenclature adjusts the third
moment or skew. Here the skew is altered by the width of the convolved exponential in the EMG.

This is also the ZDD used in the GenNLC[E] models. For the GenNLC[E]
models, a_{0}, a_{1},
and a_{3} will be identical. The a_{2}
width or second moment term will reflect a kinetic time constant. Please see the GenHVL
and GenNLC equivalence topic for further details.

[E] ZDD

a_{0} = Area

a_{1} = Center (as mean of underlying Gaussian)

a_{2} = Width (as SD of underlying Gaussian)

a_{3} = First Order Kinetic (Exponential) convolution width
