Sorry but there is a lot of infrastructure you don't have, so it won't
run as is. Plus it was cut and paste, etc. But it works 98% of the
time in its context.

Sounds reasonable, but why that one?

I need to fit a scalar (kt in the code) such that f(kt) = e_0 (a
scalar which is given from somewhere else). f() involves a bunch of
stuff (see the code, but don't bother trying to run it), but it is
I think of this as finding kt such that f(kt) - e_0 = 0, so I used a
root solver. But I hardly care so long as it works
Is there a best function for this?
I am totally unfamiliar with optimization theory, besides one
assignment on Newton's method in first semester calculus, and some
handwaving about MLE's
