Data and Hypothosis Testing Techniques

[Mats Svensson]

HI,
James Hargrove was asking about curve-fitting tools.
One tool I have found to be most useful to accomplish curve-fitting, is the
program BestFit, which is having a simple interface and is pretty
straightforward to use. The program is sold by Palisade and is available
for Windows only.
Most advanced statistical programs can also do curve-fitting on a dataset,
but you have to provide the equation for the curve. I use SPSS for this
purpose. SAS, Statistica and others can also be used.

regards

Mats Svensson

Could any reader of the digest provide me with information in books,
journals, or tutorials concerning three matters relevant to System
Dynamics, as follow:

1. Good introductions to fitting data to models or vice-versa;

2. Discussions of testing hypotheses based on assumed model structures (for
instance, predictions about responses to perturbation for a metabolic
pathway with compartments linked by first-order transfer rates). I assume
that this is similar to sensitivity testing.

3. Tools you have found to be most useful to accomplish curve-fitting?

My area of interest is in biological sciences. Thank you for suggesting
resources to deal with these questions.

Sincerely,
