Relating Least Squares method input error with output error

Abstract

The least squares method is the standard numerical method procedure for finding the best-fitting curve to a set of points, adjusting a curve looking to minimize the sum of the squares of theoffsets (hence why least squares). These residuals of the points from the curve sometimes can haveoutlying points which can cause a disproportionate effect on the fit, which can be undesirable [2].That’s this works focus. [...]
