Accelerated failure time model under general biased sampling scheme

Jane Paik Kim, Tony Sit and Zhiliang Ying.

in Biostatistics

July 2016; p ublished online March 2016 .

Journal Article. Subjects: Biomathematics and Statistics; Probability and Statistics. 6682 words.

Right-censored time-to-event data are sometimes observed from a (sub)cohort of patients whose survival times can be subject to outcome-dependent sampling schemes. In this paper, we propose...

Accounting for selection and correlation in the analysis of two-stage genome-wide association studies

October 2016; p ublished online March 2016 .

Journal Article. Subjects: Biomathematics and Statistics; Probability and Statistics. 6623 words.

The problem of selection bias has long been recognized in the analysis of two-stage trials, where promising candidates are selected in stage 1 for confirmatory analysis in stage 2. To...

in Biometrika

September 2016; p ublished online July 2016 .

Journal Article. Subjects: Biomathematics and Statistics; Probability and Statistics. 7364 words.

We consider statistical inference for a vector-valued parameter of interest in a regular asymptotic model with a finite-dimensional nuisance parameter. We use highly accurate likelihood...

in Biometrika

June 2018; p ublished online April 2018 .

Journal Article. Subjects: Biomathematics and Statistics; Probability and Statistics. 9192 words.

SUMMARY

Commonly used interval procedures for multigroup data attain their nominal coverage rates across a population of groups on average, but their actual...

Adaptive randomized trial designs that cannot be dominated by any standard design at the same total sample size

Michael Rosenblum.

in Biometrika

March 2015; p ublished online December 2014 .

Journal Article. Subjects: Biomathematics and Statistics; Probability and Statistics. 0 words.

Prior work has shown that the power of adaptive designs with rules for modifying the sample size can always be matched or improved by suitably chosen, standard, group sequential designs. A...

An adaptive two-sample test for high-dimensional means

Gongjun Xu, Lifeng Lin, Peng Wei and Wei Pan.

in Biometrika

September 2016; p ublished online August 2016 .

Journal Article. Subjects: Biomathematics and Statistics; Probability and Statistics. 9882 words.

Several two-sample tests for high-dimensional data have been proposed recently, but they are powerful only against certain alternative hypotheses. In practice, since the true alternative...

Adding experimental arms to platform clinical trials: randomization procedures and interim analyses
