How do you find curvature of "splattered" data? |

I have data that is "splattered", which means that both the
ordinate and the abscissa have noise. Actually, the data
is the real and imag part of a function of an exact
variable.
In Oct 2004, Rafael Laboissiere gave me some formulas using
svd(cov()) that worked very well to find the mean and the
slope of splattered data.
Is there some simple octave function I can use to find
curvature? In other words, find the mean, slope, *and*
curvature.
