摘要:

The planar locus where one additional point can be placed so that the correlation coefficient has the same numerical value as in the original data is found and explored. The sensitivity function of the correlation coefficient is zero on this locus. These points, however extreme, are not ‘detected’ by this coefficient. This locus suggests some restrictions on the usefulness of the correlation coefficient.

摘要:

This paper presents an alternative derivation of the expected value and variance of the sample lead to the one given in a previous paper. It deals with the case of random sampling from infinite population without replacement or from finite population with replacement. The derivation involves the use of the moment- and cumulant-generating functions, but is shorter and simpler than the original proofs.

摘要:

Response surface experimentation is an integral part of the development of a new process or product, but the relatively efficient statistical methodologies for such experimentation are underutilized by research and development scientists and engineers because of a lack of knowledge and/or understanding of these methodologies. To help to increase its utilization, a simplified approach to one such statistical methodology, known as the determination of optimum conditions, has been developed which can be used by scientists and engineers with a minimum of statistical knowledge.

摘要:

Interval estimation of a well-known measure of heterogeneity or diversity is approached by fitting a distribution by the method of moments. Exact expressions for the moments of the distribution are derived and evaluated using a computer algebra package.

摘要:

Procedures and tables for the selection of conditional double sampling plans for various entry parameters are given. A search procedure is also developed to determine the parameters of the plans when two points on the operating characteristic curve are specified.

摘要:

A table is presented for the construction and selection of tightened-normal-tightened sampling scheme of type TNT-(n1, n2;c). Efficiency of TNT-(n1, n2;c) scheme over conventional single and double sampling plans is discussed.

摘要:

In a previous paper (Bissell, 1989) some suggestions were offered for interpreting mean squares in saturated fractional designs where no independent estimate of experimental error is available. One of the methods leads to a simple numerical test of homogeneity which provides an objective accompaniment to half-Normal plotting of effects (Daniel, 1959) in 2n designs or exponential plotting of mean squares (Bissell, 1989) in 3n designs. A table of percentage points for a convenient test statistic is provided in this paper.

摘要:

Dispersion main effects and two-factor interactions are first defined and then estimated in replicated factorial experiments. A method based on Union-Intersection rules, using dispersion main effects and two factor interactions is proposed for finding the level combinations of control factors so that the response variability due to noise is minimum. Illustrative examples are also given.

摘要:

The standard procedure of carrying out a sign test of location by attribute inspection under a Curtailed Inverse Sampling Scheme (CISS), for detecting both one-and two-sided alternatives, and also its error controlling properties, has been discussed. The nature of the Average Amount of Inspection (AAI) function of the procedure in small sample situations have been examined under four different symmetric models-normal, Laplace, Cauchy and logistic. The small sample efficiency of the sign test carried out under CISS has been compared with that of the UMP test based on the sample mean, under normal model.

摘要:

In the design of experiments for estimating the slope of a response surface, slope-rotatability is a desirable property. In this paper, a measure is introduced that enables us to assess the degree of slope-rotatability for a given response surface design. The measure takes the value zero if and only if the design is slope-rotatable, and becomes larger as the design deviates from a slope-rotatable design. Examples of applying this measure to some response surface designs are also given.
