Least squares (Math.), a method of deducing from a number
of carefully made yet slightly discordant observations of
a phenomenon the most probable values of the unknown
quantities.

Note: It takes as its fundamental principle that the most
probable values are those which make the sum of the
squares of the residual errors of the observation a
minimum.
