Properties of some minimum run resolution IV designs
The regular resolution TV fractional factorial designs described in the have many desirable properties; main effect estimates are uncorrelated and are unbiased by two-factor interactions, whilst estimates of the two-factor interaction effects are limited to the identification of a significant …

Outliers and robust response surface designs
… both models. The robustness of response surface designs is also investigated. Robustness to outliers, missing data and errors in control are examined for first order models. The orthogonal designs with large second moments, such as the 2ᵏ factorial designs, are optimal in all three cases. In the …

Space-Time Codes for High Data Rate Wireless Communications
… analytic framework that supports various complex orthogonal designs with arbitrary signal cardinalities and array configurations is developed. In the second part of the dissertation, the Virginia Tech Space-Time Advanced Radio (VT-STAR) is designed, introducing a multi-antenna hardware laboratory …

The Non-Market Value of Biodiversity Enhancement in New Zealand's Planted Forests
… we analyse a balanced sample with split designs. The balanced sample is composed of 1509 choice observations equally distributed across three experimental designs, namely: orthogonal, Bayesian D-efficient and optimal orthogonal. Results from latent class logit analysis suggest that tasks …

Computer generation of designs for two-phase experiments with applications to multiplex experiments in proteomics
… in order for these eects to be evaluated. Two designs are needed for these experiments, one for each phase. Since the allocation of experimental units from the Phase 1 experiment to blocks in the Phase 2 experiment results in the block eects from the two phases interacting with one another, the …

Comparing k Population Means with No Assumption about the Variances
<p>In the analysis of most statistically designed experiments, it is common to assume equal variances along with the assumptions that the sample measurements are independent and normally distributed. Under these three assumptions, a likelihood ratio test is used to test for the difference in …
