Hi Burni

You can access the functionality by using the CurveFitter class directly.
http://imagej.nih.gov/ij/developer/api/ij/measure/CurveFitter.html

double[] x = new double [] {0, 1, 2, 3, 4, 5};
double[] y = new double [] {0, 0.9, 4.5, 8, 18, 24};

CurveFitter fitter=new CurveFitter(x, y);

fitter.doFit(1);

double[] results=fitter.getParams();

for (double d:results)
{
    print(d);
}
