I’m looking at examples for using NonlinearModelFit but I can’t see any examples for doing fits when the data has measurement error bars in two dimensions, they only seem to show how to do this with error bars along a single dimension (usually along the y-axis). For example: http://mathematica.stackexchange.com/questions/25646/using-nonlinearmodelfit-to-fit-data-with-errors, and Fit Models with Measurement Errors—Wolfram Documentation are two examples I’ve found online and in the documentation, but how do I extend this for two dimensional error bars?
Thanks!
