Weibul Growth Curve

The Weibul growth curve is defined by the equation

where is the value of the upper curve asymptote, is the value of the lower curve asymptote, is a scaling parameter, and is a parameter that controls the x-ordinate for the point of inflection for the curve at

The following constraints apply to the curve fit parameters:

• > 0, > 0, > 0, > 0
• >

The associated response feature vector is
