Harold,
Obviously the bottleneck is your objective function fn(). I have speeded up
your function by a factor of about 2.4 by using `outer' instead of sapply. I
think it can be speeded much more. I couldn't figure it out without spending a
lot of time. I am sure someone on this list-serv

Some observations -- no solution here though:
1) the code is not executable. I tried. Maybe that makes it reproducible!
Typos such as stat mod, undefined Q etc.
2) My experience is that any setup
still be acceptable.

I am trying to generalize a working piece of code for a single parameter to a
multiple parameter problem. Reproducible code is below. The parameters to be
estimated are a, b, and c. The estimation problem is such that there is one set
of a, b, c parameters for each column of the data. Hence, in
5 matches
