Hi Ben,

you can do this directly with the Fit_Polynomial plugin.
  http://imagejdocu.tudor.lu/doku.php?id=plugin:filter:fit_polynomial:start

The plugin uses the old approach for a linear fit, from the days of
programmable pocket calculators: Creating a matrix, and a very simple
matrix inversion algorithm. For well-behaved problems, with fit parameters
having the same order of magnitude, it is works well up to a few dozen fit
parameters. Otherwise, more elaborate methods such as in the JAMA package
are needed.
