How to find the sensitivity of the fitting on parameters?

Hi
I'm trying to publish an article in which I have used multirunfitter tool of NEURON. One of my reviewers has asked me to show sensitivities of the fitting on parameters. How can I do that?

Is there a solution for the above problem? Please, tell me if there is not.
Besides, latest alpha version of neuron has problem compiling in windows:
Code: Select all
./.libs/libivoc.a(ivocrand.o):ivocrand.cpp:(.text+0x6fa): undefined reference to `_nrnran123_getseq'

The principal axes and values of the praxis method are supposed to directly specify
the Hessian. However, I have found that the actual return values seem to vary quite
a bit and are useless for that. I've spent some effort to fix that but have been
unsuccessful. The only ways I know to compute the Hessian properly would be to use
a Python module or to explore the parameter space in the neighborhood of the minimum
and do your own computation of the principal axes and values.
I'll look into why the newest repository version has a problem linking ivoc and push
a fix.
