The Method of Least Squares Herv Abdi1 1 Introduction The least square methods (LSM) is probably the most popular technique in statistics. This is due to several factors. First, most common estimators can be casted within this framework.

By extension of the method of least squares, we can speak of a least square plane approximating data. If we are estimating Z from given values of X and Y, this would be called a regression plan of Z on X and Y. The normal equations corresponding to the least square plane (25) are given by:
