Mediation analyses for the effect of antibodies in vaccination
Journal of Causal InferenceWe review standard mediation assumptions as they apply to identifying antibody effects in a randomized vaccine trial and propose new study designs to allow the identification of an estimand that was previously unidentifiable. For these mediation analyses,

Smoothing-inspired lack-of-fit tests based on ranks
A rank-based test of the null hypothesis that a regressor has no effect on a response variable is proposed and analyzed. This test is identical in structure to the order selection test but with the raw data replaced by ranks. The test is nonparametric in

Sequential tests and estimates after overrunning based on $p$-value combination
Often in sequential trials additional data become available after a stopping boundary has been reached. A method of incorporating such information from overrunning is developed, based on the ``adding weighted Zs'' method of combining $p$-values.

Nonparametric control charts for bivariate high-quality processes [PDF]
For attribute data with (very) low rates of defectives, attractive control charts can be based on the maximum of subsequent groups of r failure times, for some suitable r≥1, like r=5.

Bayesian hierarchical models for analysing the spatial distribution of bioclimatic indices [PDF]
A methodological approach for modelling the spatial distribution of bioclimatic indices is proposed in this paper. The value of the bioclimatic index is modelled with a hierarchical Bayesian model that incorporates both structured and unstructured random

A Gibbs approach to Chargaff's second parity rule
Chargaff's second parity rule (CSPR) asserts that the frequencies of short polynucleotide chains are the same as those of the complementary reversed chains.

Journal of Causal InferenceInverse probability (IP) weighting of marginal structural models (MSMs) can provide consistent estimators of time-varying treatment effects under correct model specifications and identifiability assumptions, even in the presence of time-varying ...

Comparison of robust tests for genetic association using case-control studies
In genetic studies of complex diseases, the underlying mode of inheritance is often not known. Thus, the most powerful test or other optimal procedure for one model, e.g. recessive, may be quite inefficient if another model, e.g.

About the Oral Health of Bulgarian Population over 20 Years Old [PDF]
2000 Mathematics Subject Classification: 62P10, 62J12.Caries is the most widespread dental disease around the world. Thus, caries prevalence and intensity are repeatedly studied.

Multiple testing procedures under confounding
While multiple testing procedures have been the focus of much statistical research, an important facet of the problem is how to deal with possible confounding. Procedures have been developed by authors in genetics and statistics.
