regrVonPS {kpcalg}

Check if variable can be regressed to independence on its parents

Description

Uses the generalised additive model gam to non-linearly and non-parametrically regress variable V on its parents and set of variables S.

Usage

regrVonPS(G, V, S, suffStat, indepTest = kernelCItest, alpha = 0.2)

Arguments

G

adjacency matrix, for the graph

V

integer, node which we regress

S

integer(s), set we regress on

suffStat

sufficient statistics to perform the independence test kernelCItest

indepTest

independence test to check for dependence between residuals of V and S

alpha

numeric cutoff for significance level of individual partial correlation tests

Value

regrVonPS() returns the number of p-values smaller than the cutoff, i.e 0 means residuals of V are independent of all variables in S
