Description Usage Arguments Value References Examples
This is the implementation of the IGCI method for causal discovery.
1 | IGCI(x, y, refMeasure, estimator)
|
x |
The observation of the cause. |
y |
The observation of the effect. |
refMeasure |
reference measure to use: 1: uniform 2: Gaussian |
estimator |
estimator to use:1: entropy (eq. (12) in [1]), 2: integral approximation (eq. (13) in [1]). 3: new integral approximation (eq. (22) in [2]) that should deal better with repeated values |
f < 0: the method prefers the causal direction x -> y
f > 0: the method prefers the causal direction y -> x
