We identify principles and practices for writing and publishing statistical software with maximum benefit to the scholarly community.

The classical Poisson, geometric and negative binomial regression models for count data belong to the family of generalized linear models and are available at the core of the statistics toolbox in the R system for statistical computing. After reviewing the conceptual and computational features...

This paper demonstrates that citizens in seven advanced industrialized democracies generally oppose more open immigration policies, but stand ready to admit individual immigrants. Using an experimental design, we demonstrate the applicability of the “person-positivity bias” to immigration...

BARD is the first (and at time of writing, only) open source software package for general redistricting and redistricting analysis. BARD provides methods to create, display, compare, edit, automatically refine, evaluate, and profile political districting plans. BARD aims to provide a framework...

Most empirical social scientists are surprised that low-level numerical issues in software can have deleterious effects on the estimation process. Statistical analyses that appear to be perfectly successful can be invalidated by concealed numerical problems. We have developed a set of tools,...

An essential aspect of science is a community of scholars cooperating and competing in the pursuit of common goals. A critical component of this community is the common language of and the universal standards for scholarly citation, credit attribution, and the location and retrieval of articles...

The increasing volume and complexity of research, scholarly publication and research information puts an added strain on traditional methods of scholarly communication and evaluation. Information goods and networks are not standard market goods – and so we should not rely on markets alone to...
