Extended Bayesian information criteria for model selection with large model spaces (2008)
The ordinary Bayesian information criterion is too liberal for model selection when the model space is large. In this paper, we re-examine the Bayesian paradigm for model selection and propose an...
Anatomy of Escherichia coli {sigma}70 promoters (2007)
Shultzaberger, Ryan K., Chen, Zehua, Lewis, Karen A., Schneider, Thomas D.
Information theory was used to build a promoter model that accounts for the −10, the −35 and the uncertainty of the gap between them on a common scale. Helical face assignment indicated that base...
Chen, Zehua, Schneider, Thomas D.
Based on molecular information theory, 10 T7-like promoter models were built for the T7 group of phages and used to scan their host genomes and closely related genomes. 38 genomes were scanned and 12...

Molecular information theory was used to create sequence logos and promoter models for eight phages of the T7 group: T7, ϕA1122, T3, ϕYeO3-12, SP6, K1-5, gh-1 and K11. When these models...
The notion of ranked-set sampling (RSS) proposed by McIntyre provides an effective means of achieving observational economy in certain particular situations. The use of concomitant variables broadens...

Linkage Disequilibrium Mapping of Quantitative-Trait Loci by Selective Genotyping
Chen, Zehua, Zheng, Gang, Ghosh, Kaushik, Li, Zhaohai
The principles of linkage disequilibrium mapping of dichotomous diseases can be well applied to the mapping of quantitative-trait loci through the method of selective genotyping. In 1999, M. Slatkin...

Anatomy of Escherichia coli σ70 promoters
Shultzaberger, Ryan K., Chen, Zehua, Lewis, Karen A., Schneider, Thomas D.
Information theory was used to build a promoter model that accounts for the −10, the −35 and the uncertainty of the gap between them on a common scale. Helical face assignment indicated that base...
Discovery of Fur binding site clusters in Escherichia coli by information theory models
Chen, Zehua, Lewis, Karen A., Shultzaberger, Ryan K., Lyakhov, Ilya G., Zheng, Ming, Doan, Bernard, ...
Fur is a DNA binding protein that represses bacterial iron uptake systems. Eleven footprinted Escherichia coli Fur binding sites were used to create an initial information theory model of Fur...
On Expected Lengths of Predictive Intervals
We consider the problem of comparing predictive intervals for a future observation via their expected lengths at a given confidence level. A higher order asymptotic theory is developed. This...

On the Ranked-Set Sampling M-Estimates for Symmetric Location Families
Asymptotic normality, asymptotic relative efficiency, M-estimates, optimal sampling design, ranked-set sampling, robustness,
The idea of using regression quantiles to test symmetry in a linear regression model is generalized to the non-parametric regression setting. The properties of the Lp-quantiles, defined through an...

The best-r-point-average (BRPA) estimator of the maximizer of a regression function, proposed in Changchien (in: M.T. Chao, P.E. Cheng (Eds.), Proceedings of the 1990 Taipei Symposium in Statistics,...
Multiple-Interval Mapping for Quantitative Trait Loci With a Spike in the Trait Distribution
For phenotypic distributions where many individuals share a common value—such as survival time following a pathogenic infection—a spike occurs at that common value. This spike affects...
