ゴム引張強さを特性とする品質管理方式について(續報)

抄録

Further development of the preceding paper bearing the same title is attempted. That is, the present paper discusses the problem of estimating some parameters in the doubly exponential distribution which is inevitable to quality control for analyzing with tensile data of rubber whether the process of producing rubber goods has been statistically controlled. It is concluded, from the advantage to give always the unbiased and minimum-variance estimator, that the most desirable method for estimation of parameters in such a case is the, order-statistics method whose practical procedure is also described in detail.
