Newer versions with microscopic view on central blob (former)

and display of spread to sampling ratio (latter)

Also a numerical result for the continuous geometric mean of a circle

Threads called 'Least Squares Best Double Fit' (: typo corrected here)

in 'sci.math' - text - and in 'sci.math.num-analysis'

Newer version with display of spread to sampling ratio

Ideas and Material , Derivatives of Long Products , Sucked into an Idea

Sample output of Newton-Rhapson iterations on disk (converges slowly)

Theory of Moments and addendum about the Derivatives of Carriers :

all about the neighbourhood where to start the Newton-Rhapson iterations

for straight line segment / circle with points clouds

and the accompanying 'sci.math' thread

MinMax Technology is employed "for the first half"

with common Least Squares
minimization methods:

they minimize an arithmetic mean of minimal values

instead of the maximum of them.

- Least squares similarity transformation
- best root finding strategy
- A curious limit
- [ OT : that depends, though ]
