Optimal designs for dose-finding experiments in toxicity studies
dose-finding experiment locally c-optimal design multiple-objective design robustoptimal design Weibull model
2010/3/18
We construct optimal designs for estimating fetal malformation rate, prenatal death rate and
an overall toxicity index in a toxicology study under a broad range of model assumptions. We
use Weibull ...

A voting bloc is defined to be a group of voters who have similar
voting preferences. The cleavage of the Irish electorate into voting
blocs is of interest. Irish elections employ a “single transfer...

In randomized experiments, treatment and control groups
should be roughly the same—balanced—in their distributions of pretreatment
variables. But how nearly so? Can descriptive comparisons

The Cyclohedron Test for Finding Periodic Genes in Time Course Expression Studies
Cyclohedron Test Periodic Genes Time Course Expression Studies
2010/4/27
The problem of finding periodically expressed genes from time course microarray
experiments is at the center of numerous efforts to identify the molecular components
of biological clocks. We present...
Causal inference in longitudinal studies with history-restricted marginal structural models

2010/4/29
A new class of Marginal Structural Models (MSMs), History-
Restricted MSMs (HRMSMs), was recently introduced for longitudinal data
for the purpose of defining causal parameters which may often be be...
Improving power in genome-wide association studies：weights tip the scale
Bonferroni correction Genome-wide association analysis Multiple testing Weightedp-values
2010/4/26
Genome-wide association analysis has generated much discussion about how to preserve power
1 to detect signals despite the detrimental effect of multiple testing on power. We develop a weighted multi...
