Thanks for the quick reply, Wayne.
Executive Summary: I can't get a copy of the 1.52o38 jar file.

As far as I can tell, your JavaScript is pretty much identical to the Java I
must use. In psudocode:
1. Create a new CurveFitter with the x and y data.
2. Call doFit().
3. Print the results.
>It requires the latest ImageJ daily build (1.52o38),
Unfortunately, the maven repo at
https://mvnrepository.com/artifact/net.imagej/ij only goes up to 1.52n. Do
you have any idea when that will get updated? Do you push to it every once
in a while, or do you depend on them to pull?
I found the latest source code (version 1.52o40) at
https://github.com/imagej/imagej1/blob/c56624301df300ae7e30c26ad9c71ff9025eae46/ij/measure/CurveFitter.java
So I tried to download the entire ImageJ 1.x repository from
https://github.com/imagej/imagej1/tree/c56624301df300ae7e30c26ad9c71ff9025eae46but it's a non-maven project that I couldn't pull into Eclipse to generate
my own jar. I noticed the build.xml file. Um... oh, yeah, ant. I remember
using ant about a decade or two ago, but it would take me a long time to get
back up to speed. :-(
So I tried getting ImageJA (the maven version of ImageJ), but that only goes
up to version 1.52n. :-(
Finally, I tried grabbing just your new CurveFitter.java, but it broke with
the same array Index Out of Bounds exception. :-( Obviously, there are
more dependencies here--I would probably need to grab all the files manually
to make sure I have to entire fix for the Array Out of Bounds problem. :-(

fail when there was a fitting error.
The 1.52n code is breaking during the doFit() step, not during the output
printing step, though I do see how you improved CurveFitter.getResultString.
> Note that you have to construct a new CurveFitter for each fit.
Yes, I did that. Does it look like I didn't?
I hope you can create a 1.52o38 (or later) jar file for the maven repo, or
update ImageJA sometime soon.
Thanks again for your help so far.
