TLDR
In this paper, it was shown that A - and E -optimum designs minimize the effect of d in the mean square error (m.s.s) of estimable linear functions of parameters under the ordinary linear model.About:

Block Designs Robust Against the Presence of an Aberration in a Treatment-Control Setup
TL;DR: In this article, the authors considered the problem of finding designs insensitive to the presence of an outlier in a treatment-control block design setup for estimating the set of elementary contrasts between the effects of each test treatment and a control treatment.

Impacts of auxiliary information on outliers in regression
TL;DR: This paper showed that the mixed regression estimator, when observationsare subject to shift in means and variances, is uniformly superior, in terms of squared bias and variance, to the least squares estimator.

Robustness of balanced fractional 2 m factorial designs derived from simple arrays
TL;DR: This is a review of the robustness of balanced fractional 2 m factorial designs derived from simple arrays, which contains two kinds of robustness, based on the measure of sensitivity in the sense that a design should be insensitive to wild observations.
Journal ArticleDOI
Designs Robust Against Presence of an Outlier in an Analysis of Covariance Model
TL;DR: In this article, an attempt has been made to find robust designs in a block design set-up with covariates, when there is one single wild observation in the study variable.

Optimum Experimental Designs
TL;DR: In this article, the authors discuss certain basic considerations such as the nonoptimality of the classical symmetric (balanced) designs for hypothesis testing, the optimality of designs invariant under an appropriate group of transformations, etc.
On discrete distributions arising out of methods of ascertainment
TL;DR: In this paper, the frequency of families with both parents heterozygous for albinism and having no albino children was investigated and the actual frequency of the event was not ascertainable.
