How can statisticians support refugees?

In this special issue, we aim to lay the groundwork for statistical support for refugee populations. We hope this special issue will serve as a valuable resource for the statistics community. We also want to highlight the broader value of statistics …

Mechanisms of exercise-induced reduction in peripheral arterial stiffness

Peripheral arterial stiffness measured with pulse wave velocity (PWV) is reduced 5-min after an acute bout of dynamic exercise. The mechanism for the reduction in peripheral arterial stiffness is unknown. We hypothesized that increased blood flow …

Robust variance estimation in small meta-analysis with the standardized mean difference

Conventional random-effects models in meta-analysis rely on large sample approximations instead of exact small sample results. While random-effects methods produce efficient estimates and confidence intervals for the summary effect have correct …

Effect sizes in ANCOVA and difference-in-differences designs

It is common practice in both randomized and quasi-experiments to adjust for baseline characteristics when estimating the average effect of an intervention. The inclusion of a pre-test, for example, can reduce both the standard error of this …

An evaluation of statistical methods for aggregate patterns of replication failure

Several programs of research have sought to assess the replicability of scientific findings in different fields, including economics and psychology. These programs attempt to replicate several findings and use the results to say something about …
