TL;DR: In this article, the mathematical properties of a class of functions called linear sensitivity measures are investigated for maintaining the statistical confidentiality of respondents to a census or statistical survey such as an establishment-based economic survey.

TL;DR: A ‘pooling sets’ type of algorithm is developed and shown to be valid for computing an isotonic regression function for a general quasi-order and works best when the quasi- order is complex and the objective function is nearly isotonic.

TL;DR: In this paper, the authors extended the bounded-width sequential confidence intervals and sequential tests for regression parameter based on M-estimators to the case of jump-discontinuities.

TL;DR: In this article, the determination of a stopping rule for the detection of the time of an increase in the success probability of a sequence of independent Bernoulli trials is discussed, and the results indicate that the detection procedure is quite effective.

TL;DR: In this paper, the speed of convergence of kernel estimators of mixed partial derivatives is investigated for various asymptotic properties, including asymPTI, mean square consistency, strong consistency and asym PTI normality.

TL;DR: In this article, two distinct methods have been proposed for the construction of effect-wise orthogonal factorial designs, which ensure desirable properties with respect to main effects and require a smaller number of replications than any of the existing methods.

TL;DR: In this paper, an explicit expression for the characteristic polynomial of the information matrix M T of a balanced fractional 3 m factorial (3 m -BFF) design T of resolution V is obtained by utilizing the algebraic structure of the underlying multidimentional relationship.

TL;DR: In this paper, some new families of semi-regular or regular group divisible designs are presented, together with new nonisomorphic solutions for some known group-divisible designs.

TL;DR: In this article, the authors obtained search designs with reasonably small number of treatments which permit the estimation of the general mean and main effects and search of one more unknown possible nonzero effect among two and three factor interactions in 2 m factorial experiments.

TL;DR: In this paper, it is shown that the test selected for use at each point in the sequence should depend on which measure is used and two suggestions of Gower and Payne (1975), regarding test selection, are shown to be appropriate only to the new measure.

TL;DR: In this article, the optimality of two-factor experimental designs is studied in the dual senses of estimating contrasts in the parameters for each of the factors, and the results hold for a wide class of optimality criteria (not merely D -, A - and E -optimality), which must satisfy a functional equation obtained in connection with their method.

TL;DR: It will be shown that for some given integers d, there exists no solution of the linear programming except a solution which is obtained using a flat in a finite projective geometry.

TL;DR: A nest with parameters (r,k,λ)→(r′,k′,λ′) is a BIBD on (b,v, r, k,λ), where each block has a distinguished sublock of cardinality k as mentioned in this paper.

TL;DR: The design matrix for a randomized response (RR) design provides a description of the random transformation that is applied to the statement of the true state of the respondent, before a reply is made to the interviewer as mentioned in this paper.

TL;DR: A technique where long codes (65000-element or longer) as well as short codes can systematically be generated with desired properties and several examples of the use of the technique for generating codes with other desired properties are outlined.

TL;DR: The concept of balance in factorial design is discussed and results are given which enable the degree of balance for generalised cyclic designs to be determined in this paper, where the authors also give a detailed analysis of the intra-block analysis of such designs.

TL;DR: In this paper, the authors give a general procedure for constructing orthogonal F-squares of order n from an O(n, k, s, 2) and an OL(s, t) set, where n is not necessarily a prime or prime power.

TL;DR: In this paper, the spatial sampling designs suggested by Quenouille (1949) are investigated under a number of trend assumptions, namely a linear trend, linear trend and periodic variation, and spatially correlated populations.

TL;DR: In this paper, the second order asymptotic linearity of the pertaining linear rank statistics was obtained for the score-generating function ϕ under the assumption that ϕ has some jump-discontinuities.

TL;DR: In this paper, an account of the behavior of the independent-samples t -test when applied to homoschedastic bivariate normal data is presented, and a comparison is made with the paired-sample t-test, as though the samples were independent.

TL;DR: For the inverse of mean, a class of estimators with finite moments is considered and its properties are analyzed in the context of normal and non-normal populations in this paper, where the properties of the estimators are compared in the presence of different populations.

TL;DR: In this paper, necessary and sufficient conditions for the simple least squares estimator to coincide with the best linear unbiased predictor were developed for a general linear model and are generalizations of the condition given by Watson (1972).

TL;DR: In this paper, the authors consider tests for scale parameters when the underlying distribution belongs to the class of spherically symmetric laws and show that the usual normal-theory tests are not only invariant tests but also exactly robust with respect to this class of laws.

TL;DR: In this article, a necessary and sufficient condition for a two-associate-class PBIB design to be connected was established in terms of its parameters, and a necessary condition was established for the design to satisfy its parameters.

TL;DR: In this paper, it is shown that, in the discrete case, the Markov property does not hold good and that the probability of ties is not equal to zero in the continuous case, whereas it is not true when the distribution is discrete.

TL;DR: In this article, the authors present the generalized Jackknife technique for reducing bias and show how the generalized jackknife could be interpreted by the same method. And they discuss a method of constructing unbiased ratio estimators.

TL;DR: In this paper, the authors considered the problem of devising a single stage procedure for selecting the treatment combination associated with the largest interaction in a two-factor r fx×c experiment having independent normally distributed observations with common known variance.

TL;DR: In this paper, the stability of a slightly modified version of the usual jackknife variance estimator is evaluated exactly in small samples under a suitable linear regression model and compared with that of two different linearization variance estimators.

TL;DR: A criterion showing when the orbit of a subgraph of a given rank 3 graph forms a block design, is given.

TL;DR: In this paper, a class of rank-order tests for linear regression surfaces is considered, and their asymptotic efficiency relative to the general likelihood ratio test is derived. But their results are restricted to the case where the surfaces are parallel to one another.
