I have a data surface that I'm fitting using SciPy's leastsq function. I would like to have some estimate of the quality.. like to have some estimate of the quality of the fit after leastsq returns. I'd expected that this would be included as a return.. data fitting share improve this question If you call leastsq like this import scipy.optimize p cov infodict mesg ier optimize.leastsq..

scipy.optimize.leastsq with bound constraints

http://stackoverflow.com/questions/9878558/scipy-optimize-leastsq-with-bound-constraints

with bound constraints I am looking for an optimisation routine.. constraints can easily be made quadratic and minimized by leastsq along with the rest. Say you want to minimize a sum of 10 squares.. 0 .. 1 and positive outside like a _ _ _ tub. If we give leastsq the 13 long vector f0 p f1 p ... f9 p w tub p0 w tub p1 w tub..
