Some view of statistical method in engineering
通夫 上田, 文隆 今里 · Kagoshima University Repository · 1967
Mere numerical accuracy or mathematical rigidity as formal logic is not at any time valuable just as it is for engineering or technology. When we once treated any problem of engineering with mathematical method, we must again observe the result in view of the original point, should catch the actual meaning of it. On the contrary, we find some simple ways which is almost valueless as formal logic yet sometimes of much practical use in engineering. Here the authors offer an example concerning a designed experiment of orthogonal arrey. There, elimination of significant factors is shown. Both practical meaning and evaluation of interactions are considered. The paper is rather for beginners, not for experts.
