Hello,
I have a few questions related to using differential equation models.
I am going to be a little general, as I have different differential equation
models that I may use.
Basically, I would like to do a least squares fit of data to a model consisting
of a system of differential equations in order to determine the model
parameters of best fit.
For instance, I might use the system:
dy/dt = -k1x1 - k2x1x2
dx1/dt = k3y - k4x2
dx2/dt = k5y + k6x1
I would then collect data on y, x1, x2 at different times.
The goal in this situation would be to determine k1,k2,k3...
Are there any functions in S+, or functions that I could import into S+ that
would work with differential equations in this manner.
Sorry if this is at all confusing, as I am still trying to understand it myself.
Thanks!
Clark Kogan
