Then, if my estimation is not at one of the bounds of the constraint, I can use the dfs/bfgs Hessian that is calculated in the unconstrained optimization, to derive the standard errors in the way Roger wrote above. ... WebSep 14, 2013 · More specifically, from this forum post it seems that octave's fminunc uses some form of BFGS (couldn't find a more authoritative reference). So scipy.optimize.fmin_bfgs seems like the closest parallel to fminunc. – alecbz Dec 23, 2013 at 22:58 Add a comment 2 Implemented as below and getting similar result of octiva:
