Description

Gaussian conditional independence test. See the zf function in the bnlearn package for more details.

Usage

zf(x, y, S, suffStat)

Arguments

x, y, S

It is tested, whether x and y are conditionally independent given the subset S of the remaining nodes. x, y, S all are integers, corresponding to variable or node numbers.

suffStat

the data matrix with rows are samples and columns are the variables.
