- The arithmetic in ``
world'' is that of full
matrices which are 
where n is number of parameters.
- In ``linear'' case (
linear in components of
, 
quadratic in components), minimization
requires single solution of equations
- In ``nonlinear'' case (
nonlinear in 
), one must
iteratively solve 
.
- Note that one expands
up to linear term which gives a quadratic
approximations to 
.
- Thus, need to calculate
- where ``value''
