This paper examines the statistical properties of uniform design for stated choice modeling. Estimation efficiency, prediction efficiency and test power (i.e., the ability to pick up significant effects or exclude insignificant effects) are selected as measures of statistical properties. Both uniform design and orthogonal design are used to generate profiles. The major experimental design strat...

-This paper presents an enhanced Latin Square Genetic Algorithm (LSGA). It makes the chromosomes to be more sensible to their surrounding regions. The algorithm applies orthogonal design method to every chromosome in the population to detect chromosomes with high fitness values in the surrounding regions. Orthogonal design method makes it more concise and direct to find the delegate to represen...

BACKGROUND Experimental designs constitute a vital component of all Stated Choice (aka discrete choice experiment) studies. However, there exists limited empirical evaluation of the statistical benefits of Stated Choice (SC) experimental designs that employ non-zero prior estimates in constructing non-orthogonal constrained designs. This paper statistically compares the performance of contrasti...

Spectral efficiency improvement is a key focus in most wireless communication systems and achieved by various means such as using large antenna arrays and/or advanced modulation schemes signal formats. This work proposes to further improve spectral through combining non-orthogonal spectrally efficient frequency division multiplexing (SEFDM) with index (IM), which can efficiently make use of the...

The design method of orthogonal test is commonly used in engineering test. It is very effective when many factors influences on one test. Orthogonal table experimental design is necessary to simplify the test procedure, to reduce the number of tests, and to improve test efficiency. By the orthogonal test, a level of each factor can be chosen to form the optimal production conditions. But in the...

This paper describes a state space discretization scheme based on statistical experimental designs generated from orthogonal arrays of strength three with index unity. Chen et al. (1997) used this eecient discretization scheme to approximately solve high-dimensional continuous-state stochastic dynamic programming (SDP). Prior methods discretized the state space with a nite grid. The orthogonal ...
