Experimental design matters for statistical analysis: how to handle blocking
Pest Management Science, 2017AbstractBACKGROUNDNowadays, evaluation of the effects of pesticides often relies on experimental designs that involve multiple concentrations of the pesticide of interest or multiple pesticides at specific comparable concentrations and, possibly, secondary factors of interest.

Design and statistical analysis of a new chaos block cipher for WSN
2010 IEEE International Conference on Information Theory and Information Security, 2010In this paper, a chaotic block cipher based on chaos box is proposed for WSN. First, the pors and cons of WSN existing encryption algorithm is analysed. Then, a new encryption algorithm for WSN is introduced. Finally, conclusion is made by comparing with RC5 and RC6 at statistical performance. Data shows this encryption scheme has good performance.

General Block Designs and Their Statistical Properties
2000According to one of the basic principles of experimental design, the randomiza-tion principle (see Section 1.1), the experimental units (plots) are to be random-ized before they enter the experiment. Suppose that to apply a general block design, in the sense of Section 2.2, randomization is performed as described by Nelder (1954), i.e., by randomly ...

On the Use of a Friedman-Type Statistic in Balanced and Unbalanced Block Designs
Technometrics, 1981Distribution-free tests and multiple comparison procedures are considered for randomized block designs. A general Friedman-type statistic is defined that is usable in almost any block design with arbitrary missing data structure. For balanced incomplete block designs a multiple comparison procedure and exact tables are given for a statistic equivalent ...

A Comparison among Combination-Based Permutation Statistics for Randomized Complete Block Design
Communications in Statistics - Simulation and Computation, 2012It is well known that a best permutation test for all population distributions P does not generally exist, because the most powerful unbiased permutation test is a function of the population distribution P which is assumed to be unknown (Pesarin and Salmaso, 2010).

Some Statistical Properties of Nested Block Designs
1998Nested block designs in a wide sense are newly discussed from a statistical point of view. Some statistical properties of such designs are presented with some constructions. The corresponding properties of the usual nested block designs in the literature are included as a special case.

22 Block designs: Their combinatorial and statistical properties
1996Publisher Summary This chapter discusses the combinatorial and statistical properties of block designs. The theory of discrete designs is intimately related to many other areas of combinatorial theory. Block designs have opened up many interesting and challenging problems in combinatorial mathematics. The fundamental problems related to block designs,

Studentized robust statistics in multivariate randomized block design
Journal of Nonparametric Statistics, 1998Multiresponse experiments in randomized block design are considered. Statistical procedures of the test and estimation, based on studentized robust statistics, for location parameters in the models are proposed. Large sample properties of their procedures as the number of blocks tends to infinity are investigated.

Incomplete Block Designs for Genetic Testing: Statistical Efficiencies with Missing Observations
Forest Science, 1999Abstract Missing observations are common in forest genetic field trials and are expected to reduce statistical efficiencies of any applied field designs. Such reductions could lower the presumed efficiency and other benefits of implementing any incomplete block designs (ICBs).

Abstract We evaluated the use of a Latin Square design for assessing the performance of bycatch reduction devices (BRDs). We wanted to ensure the most precise result possible given limited resources, high variability and the need to detect small differences.
