Hi Yohan
I see that I'm not alone wondering a bit about what you'd like to do.
A mathematically solid and readily available technique to corner
mathematical rounding errors and other errors of operation is called
Interval Analysis.
For matlab there's INTLAB. See:
http://www.ti3.tu-harburg.de/~rump/intlab/
I'm sure it could be converted to Scilab without big trouble. Maybe I
even have an old one laying around (??) somewhere ... maybe.
Yes indeed, here : http://www-sop.inria.fr/coprin/logiciels/Int4Sci/
The thing is I don't see how to use these tools to do what Yoahn wants
to do.
I think I have the same kind of issues than Yoahn (I've done a fit, how
good is it as compare to another one, and what kind of "confidence" or
"error bar" should I associate to each parameter).
Could you tell us how we can use interval analysis to adress this (just
curious, it's a bit far from my field of expertise)?
Cheers,
Antoine
