Conditional independence testing
WebIn this section, we would like to introduce (conditional) independence tests in causal-learn. Currently we have Fisher-z test 1 , Missing-value Fisher-z test, Chi-Square test, Kernel-based conditional independence (KCI) test and independence test 2 , and G-Square test 3. Fisher, R. A. (1921).

WebApr 11, 2024 · We propose a characteristic function based test for conditional independence, applicable to both cross-sectional and time series data. We also derive a class of derivative tests, which deliver model-free tests for such important hypotheses as omitted variables, Granger causality in various moments and conditional uncorrelatedness.
