The Method of Least Squares - Williams College

3 The Method of Least Squares 4 1 Description of the Problem Often in the real world one expects to find linear relationships between variables. For example, the force of a spring linearly depends on the displacement of the spring: y = kx (here y is the force, x is the displacement of the spring from rest, and k is the spring constant). To test
