Experimental designs for population hybridization studies
In this investigation, experimental designs were developed for population hybridization studies. The objective of all of these designs was to obtain information about (i) the general combining ability of populations, (ii) the specific combining ability of population crosses, (iii) the general …

Improving Genetic Analysis with Augmented Experimental Designs
… the field variation due to the heterogeneity of experimental units. Ineffective control of field variation in genetic analysis may increase the residual variance and results in biased estimation of genetic effects. This research addressed this problem by extending the genetic models with …

Experimental Designs and Analysis of Data for Mixtures
… by a synthetic example. Concentric shell designs recently developed by Doehlert are outlined and their relationship to balanced incomplete blocks, Scheffe's designs and Hadamard matrices is given. Draper and Lawrence have developed more sophisticated designs using techniques worked out by …

Randomization analysis of experimental designs under non standard conditions
Often the basic assumptions of the ANOVA for an experimental design are not met or the statistical model is incorrectly specified. Randomization of treatments to experimental units is expected to protect against such shortcomings. This paper uses randomization theory to examine the impact on the …

Optimal experimental designs for two-variable logistic regression models
… modeled using the logistic regression model. Experimental design theory for the logistic model appears to be increasingly important as experimentation becomes more complex and expensive. The optimal design work is extremely valuable in areas such as biomedical and environmental applications. …

Improving Response Characteristics of Split Ring Resonators Using Experimental Designs
… between the efficiency and accuracy of different experimental design models. This study demonstrated that a full factorial design gives more dependable results than a central composite design even though more experiments are required. This result is due to the more extensive coverage of the design …

Experimental designs for efficient free-space multi-spatial-mode optical communication
… This thesis aims to lay the groundwork for an experimental design to achieve efficient spatial-PPM free-space optical communication using 1550 nm light at the single photon level. We focus on presenting and evaluating a transmitter-receiver design by giving a precise characterization of its …

Optimal Experimental Designs for the Poisson Regression Model in Toxicity Studies
Optimal experimental designs for generalized linear models have received increasing attention in recent years. Yet, most of the current research focuses on binary data models especially the one-variable first-order logistic regression model. This research extends this topic to count data models. …

Optimal experimental designs for estimating the slope of a response surface
… the most part these criteria have led to optimal designs for predicting response. In many applications of response surface methodology, however, the primary experimental objective can best be fulfilled by estimating the slope of the response surface. This would be the case, for example, in …

Optimal experimental designs for the estimation of thermal properties of composite materials
… thermal properties and to then utilize these designs in the development of an estimation procedure to determine the effective thermal properties (thermal conductivity and volumetric heat capacity). The experiments were optimized by choosing experimental parameters that maximize the temperature …

Examining charter school policy and public school district resource allocation using multiple quasi-experimental designs
This project incorporates three different examinations of the relationship between charter schools and public school districts and district-run public schools. Charter schools, publically funded and privately run, are thought to improve performance in district-run public schools through a variety …

Experimental verification of optimal experimental designs for the estimation of thermal properties of composite materials
… which do not have the flexibility to be experimentally tested in multiple configurations. In order to produce reliable and accurate thermal property estimates, the experiments must be carefully developed. A carefully designed experiment maximizes the sensitivity of the temperature …

Effect Sizes for Single Case Experimental Designs and Their Utility for a Meta-Analysis: A Simulation Study
… for use in meta-analyses involving Single Case Experimental Designs (SCEDs). SCEDs are a set of experimental designs which produce data akin to short interrupted time-series, where observations may not be independent due to autocorrelation. This thesis evaluated the statistical properties of …

Optimum experimental designs for models with a skewed error distribution: with an application to stochastic frontier models
In this thesis, optimum experimental designs for a statistical model possessing a skewed error distribution are considered, with particular interest in investigating possible parameter dependence of the optimum designs. The skewness in the distribution of the error arises from its assumed …

The ACEWEM computational laboratory : an integrated agent-based and statistical modelling framework for experimental designs of repeated power auctions
This research work develops a novel framework for experimental designs of liberalised wholesale power markets, namely the Agent-based Computational Economics of Wholesale Electricity Market (ACEWEM) framework. The ACEWEM allows to further understand the effect of various market designs on market …

Sequential robust response surface strategy
… variables. Many criteria exist for selecting an experimental design for the controllable variables. A good choice of a design is one that may not be optimal in a single sense, but rather near optimal with respect to several criteria. This robust approach can lend well to strategies that involve …

Embracing heterogeneity in multi-donor scRNAseq data: scalable inference of multi-scale heterogenity
… multi-scale heterogeneity in large multi-donor experimental designs. I applied this model to analyse data derived from peripheral blood mononuclear cells from a large number of human donors, demonstrating that my approach is able to capture heterogeneity at multiple levels within such …
