class NLS_ODE extends Predictor with Error

Given an Ordinary Differential Equation 'ODE' parameterized using the vector 'b' with Initial Value 'IV' 'y0', estimate the parameter values 'b' for the ODE using weighted Non-linear Least Squares 'NLS'.

ODE: dy/dt = f(t, y) IV: y(t0) = y0

Times series data: z(t0), z(t1), ... z(tn)
