[ascl:1601.002] Hyper-Fit: Fitting routines for multidimensional data with multivariate Gaussian uncertainties

The R package Hyper-Fit fits hyperplanes ( and creates 2D/3D visualizations (hyper.plot2d / hyper.plot3d) to produce robust 1D linear fits for 2D x vs y type data, and robust 2D plane fits to 3D x vs y vs z type data. This hyperplane fitting works generically for any N-1 hyperplane model being fit to a N dimensional dataset. All fits include intrinsic scatter in the generative model orthogonal to the hyperplane. A web interface for online fitting is also available at
