Authors' Reply
Statistics in Medicine, 31(29), 4143–4144.
TL;DR:
The similarity between the sequential parallel design and the three-phase design published earlier and the score statistics proposed by Huang and Tamura and Ivanova et al had type I error probabilities close to the nominal rate even for sample sizes as low as nD 50, suggesting that exact tests may not be necessary in many settings.

Maximum likelihood estimation of time to first event in the presence of data gaps and multiple events
STATISTICAL METHODS IN MEDICAL RESEARCH, 25(2), 775–792.
author keywords: Accelerated life test; censored data; continuous ECG monitoring; missing data; survival analysis; multiple events
MeSH headings : Data Interpretation, Statistical; Humans; Likelihood Functions; Myocardial Infarction / mortality; Myocardial Infarction / therapy; Time Factors
TL;DR:
The proposed gap likelihood method is shown to be more efficient and less biased than interval censoring and more efficient than right censoring if data gaps occur early in the monitoring process or are short in duration.

Estimation of treatment effect for the sequential parallel design
STATISTICS IN MEDICINE, 30(30), 3496–3506.
author keywords: linear combination estimate; constrained maximum likelihood; mean square error; bias; coverage
MeSH headings : Bias; Biostatistics; Depressive Disorder, Major / drug therapy; Humans; Likelihood Functions; Linear Models; Mental Disorders / drug therapy; Randomized Controlled Trials as Topic / statistics & numerical data; Selective Serotonin Reuptake Inhibitors / therapeutic use; Tetrahydrofolates / therapeutic use; Treatment Outcome
TL;DR:
Simulations and a real data example suggest that there can be substantial gains in precision by incorporating data from both phases of the sequential parallel clinical trial, and the potential gains appear to be greatest in moderate-sized trials, which would typically be the case in phase II trials.

FSR methods for second-order regression models
COMPUTATIONAL STATISTICS & DATA ANALYSIS, 55(6), 2026–2037.
author keywords: Bagging; False selection rate; Model selection; Response optimization; Variable selection
TL;DR:
Forward selection algorithms are developed that enforce natural hierarchies in second-order models to control the entry rate of uninformative effects and to equalize the false selection rates from first-order and second- order terms.

P-Value Precision and Reproducibility
AMERICAN STATISTICIAN, 65(4), 213–221.
author keywords: Log p-value; Measure of evidence; Prediction interval; Reproducibility probability
TL;DR:
It is shown that p-values exhibit surprisingly large variability in typical data situations, and the use of *, **, and *** to denote levels 0.05, 0.01, and 0.001 of statistical significance in subject-matter journals is about the right level of precision for reporting p- values when judged by widely accepted rules for rounding statistical estimates.

Fast FSR Variable Selection with Applications to Clinical Trials

MeSH headings : Biometry / methods; Clinical Trials as Topic; Computer Simulation; Data Interpretation, Statistical; Effect Modifier, Epidemiologic; Models, Statistical; Proportional Hazards Models; Regression Analysis
TL;DR:
A new version of the false selection rate variable selection method that requires no simulation is developed that allows the tuning parameter in forward selection to be estimated simply by hand calculation from a summary table of output even for situations where the number of explanatory variables is larger than the sample size.

MeSH headings : Algorithms; Arrhythmias, Cardiac / chemically induced; Arrhythmias, Cardiac / prevention & control; Contraindications; Cross-Over Studies; Drug Evaluation / statistics & numerical data; Electrocardiography; Humans; Pharmaceutical Preparations; United States
TL;DR:
New bounds for the maximum, both analytical and bootstrap‐based, that are lower but still achieve correct coverage in the context of crossover and parallel designs for the most realistic portions of the parameter space are proposed.

TL;DR:
This paper focuses on hypothesis testing in a dose–response framework and shows that increased power is possible by using a mixture model where both the logit of the response rate and the response mean are linear functions of the dose level.
