New solution of linear regression equations derived from related plan experiment

Dragoslav R. Petroviæ, PhD (Eng)[1])

 

Dimensional reasoning is a very powerful tool for determining the exponents , not requaring any experimental work except for a coefficient  equation  where  are mechanical system parameters. It has enabled us to deduce the parameter relationships even with very little knowledge, and certainly no mechanical analysis, of the mechanical system phisical problem. However,it is inadequate in problems where there are  parameters to be included on the right-hand side.        
This paper is the result of an investigation process for determining exponents  and coefficient  in the above equation putting no restriction as for the number of parameters and actual problems asociated with it. One of the significant results eliminating need for any numerical or analytical methods for solving a system of ordinary linear equations as a means of determining of the exponents  and corrective factor -coefficient . It is based on the new construction plan experiment, that is when the order and number of variables is concerned, in close relation with linear regression equations.

 

Key words: linear regression, system linear equations, experiments plan.
