Dual total correlation

Dual total correlation is a concept from information theory and statistics, often related to the analysis of complex systems and their information structures. While it is less commonly referenced than some other measures, it can be understood in the context of how information is measured and shared among variables in a system. ### Background Concepts 1. **Total Correlation**: Total correlation is a measure of the amount of information that is shared among multiple random variables.
