Wen Liang Wu, Yao Zhang, Zai Qi Fu, Li Zhang · Applied Mechanics and Materials · 2013
We present a new least square method called Symmetrical Least Square Method (SLSM) for linear fitting. It is symmetrical to two groups of fitted trial data. With SLSM, the slope and its uncertainty of a fitting line are given on zero-crossing linear fitting. The preliminary application of the SLSM supports that it has less uncertainty than routine least square method.
