[SciPy-User] Revisit Unexpected covariance matrix from scipy.optimize.curve_fit
Fri Feb 22 16:28:26 CST 2013
Thanks for the clarifications and discussion here. Just to close this
out, I updated the notebook with the suggestion from Christoph (which
is formally the same as the one from Eric Moore). This gives the
I just made a documentation update PR
(https://github.com/scipy/scipy/pull/446). Hopefully this is not
controversial and can be merged. Then Christoph and/or I will make a
pull request to add a scale_pcov parameter.
