## S3 method for class 'lvm'
dsep(object, x, cond = NULL, return.graph = FALSE, ...)

Arguments

object	lvm object
x	Variables for which to check for conditional independence
cond	Conditioning set
return.graph	If TRUE the moralized ancestral graph with the conditioning set removed is returned
...	Additional arguments to lower level functions

Details

The argument 'x' can be given as a formula, e.g. x~y|z+v or ~x+y|z+v With everything on the rhs of the bar defining the variables on which to condition on.

Examples

m <- lvm(x5 ~ x4+x3, x4~x3+x1, x3~x2, x2~x1)
if (interactive()) {
plot(m,layoutType='neato')
}
dsep(m,x5~x1|x2+x4)
dsep(m,x5~x1|x3+x4)
dsep(m,~x1+x2+x3|x4)
