three-dimensional Euclidean space.Comment: AmSTeX, 6 pages, amsppt styl
On linear regression in three-dimensional Euclidean space
The three-dimensional linear regression problem is a problem of finding a
spacial straight line best fitting a group of points in three-dimensional
Euclidean space. This problem is considered in the present paper and a solution
to it is given in a coordinate-free form.Comment: AmSTeX, 4 pages, amsppt styl
On cylindrical regression in three-dimensional Euclidean space
The three-dimensional cylindrical regression problem is a problem of finding
a cylinder best fitting a group of points in three-dimensional Euclidean space.
The words best fitting are usually understood in the sense of the minimum root
mean square deflection of the given points from a cylinder to be found. In this
form the problem has no analytic solution. If one replaces the root mean square
averaging by a certain biquadratic averaging, the resulting problem has an
almost analytic solution. This solution is reproduced in the present paper in a
coordinate-free form.Comment: AmSTeX, 10 pages, amsppt styl
ALGORITHMS FOR LAYING POINTS OPTIMALLY ON A PLANE AND A CIRCLE.
Abstract. Two averaging algorithms are considered which are intended for choosing an optimal plane and an optimal circle approximating a group of points in threedimensional Euclidean space. 1. Introduction. Assume that in the three-dimensional Euclidean space E we have a group of points visually resembling a circle (see Fig. 1.1). The problem is to find the best plane and the best circle approximating this group of points. Any plane in E i
