Code, Apps, and Tutorials

This research topic contains a list of publications describing tutorials, code, or stand-alone applications or packages for use by applied researchers and quantitative methodologists alike.

Most of our methodological research papers include some custom coding or implementation of a statistical technique or method. Many newer papers outside of this research topic include a repository (e.g., on the Open Science Framework) that contains relevant code. Refer to the original paper or the Publications page for details.

Additional resources or tutorials may be available on upcoming sections of this website.
