The credibility of quantitative social science benefits from policies that increase confidence that results reported by one researcher can be verified by others. Concerns about replicability have increased as the scale and sophistication of analyses increase the possible dependence of results on...

Commentators appreciate the benefits of developing improved standards for replicating quantitative results in sociology. Nonetheless, reservations remain, and the author addresses several of them and explains why improved replication standards do not endanger participant confidentiality, do not...

Although Stata has made estimating regression models for categorical and count outcomes virtually as fast and easy as estimating the familiar regression model for continuous outcomes, interpreting the results from the former is complicated by the nonlinear relationship between the independent...

In recent decades, an interdisciplinary quality assurance (QA) movement has emerged in health care studies, which has included increased attention to medical errors. Implicit in this QA effort is a conflict between (1) external agents encouraging the medical profession to adopt strategies for...
