The most probable value (MPV) estimation of an observation set is the one which that minimizes the sum of the squares of the residuals, Equations C-1 and C-2.

Equation C-1
Equation C-2
  v: Residual
o: Observation

Combining Equations C-1 and C-2 gives Equation C-3; its only unknown is the MPV. To minimize a function, its first derivative is set equal to zero, Equation C-4, and solved for the unknown.

Equation C-3
Equation C-4

Because the derivative is set to zero, we will refer to this as the Direct Minimization method.
