SODR

 
Fits a model to data, primarily for instances when the explanatory as well as the
response variables have significant errors. Minimizes the sum of the squares of
the weighted orthogonal distances between each data point and the curve
described by the model equation. Can also be used to solve the ordinary least
squares problem, where all the errors are attributed to the observations of the
dependent variable.
