Contributor to the gets package for general-to-specific model selection and indicator saturation methods in R. You can also find some unpublished enhancements and bug fixes on my GitHub fork.
r2sls package for outlier detection and testing in two-stage least squares models. Allows for various algorithms to detect outliers in the sample, conduct statistical tests for the presence of outliers, provides valid inference under the null hypothesis that there are no outliers, and tests for whether the effect of outliers in the parameter estimates are significant. Not a public repository yet.
ivgets package for general-to-specific model selection and indicator saturation methods in two-stage least squares models. You can find an illustration below or visit the external app. The app is still under development but mostly functional already.
