Recently I began writing a program to do a monte carlo simulation of an
NMR experiment. The whole routine is attached (I hope that works.) The
problem is this:
I perform a NonlinearFit utilizing an exponential function of the form
Exp[-a*x]. The nonlinear fit gives me back an equation, something like
1*E(-a*x). I want to extract the a parameter out of the equation and do
two things with it. Because I am performing this simulation several
(thousand) times, I want to know the standard deviation of the a
parameters. Second, I would like to get an average of the terms
(without having to use the last two lines of my code). If anyone out
there could help me out, I would greatly appreciate it; I'm really
stuck.
(PS, if you try to run my code, you may want to change the number of
iterations to 10 or so. 10000 iterations takes a couple of hours.)

Mathematica-Compatible Notebook
This notebook can be used on any computer system with Mathematica 3.0,
MathReader 3.0, or any compatible application. The data for the
notebook starts with the line of stars above.
To get the notebook into a Mathematica-compatible application, do one of
the following:
* Save the data starting with the line of stars above into a file
with a name ending in .nb, then open the file inside the application;
* Copy the data starting with the line of stars above to the
clipboard, then use the Paste menu command inside the application.
Data for notebooks contains only printable 7-bit ASCII and can be sent
directly in email or through ftp in text mode. Newlines can be CR, LF
or CRLF (Unix, Macintosh or MS-DOS style).
NOTE: If you modify the data for this notebook not in a Mathematica-
compatible application, you must delete the line below containing the
word CacheID, otherwise Mathematica-compatible applications may try to
use invalid cache data.
