regrVonPS: 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
