Information-Theoretic Measures for Revealing Variable Interactions
infoxtr is an R package for analyzing variable interactions using information-theoretic measures. Originally tailored for time series, its methods extend seamlessly to spatial cross-sectional data. Powered by a pure C++ engine with a lightweight R interface, the package also exposes its headers for direct integration into other R packages.
Refer to the package documentation https://stscl.github.io/infoxtr/ for more detailed information.
