Define double logistics, piecewise logistics and many other functions to curve fit VI time-series
Logistic
The traditional simplest logistic function. It can
be only used in half growing season, i.e. vegetation green-up or senescence
period.
doubleLog.Zhang
Piecewise logistics, (Zhang Xiaoyang, RSE, 2003).
doubleAG
Asymmetric Gaussian.
doubleLog.Beck
Beck logistics.
doubleLog.Gu
Gu logistics.
doubleLog.Elmore
Elmore logistics.
doubleLog.Klos
Klos logistics.

All of those function have par
and formula
attributes for the
convenience for analytical D1 and D2
