Researchers have developed a new framework for conditional independence testing specifically designed for multivariate, nonstationary, and nonlinear time series data. This method addresses limitations of traditional linear models by enabling the capture of complex nonlinear dynamics. The framework utilizes time-varying nonlinear regression and a strong Gaussian approximation to accurately estimate relationships within a single time series realization. AI
