missing.pairwise Function (GPL)

Syntax

missing.pairwise()

Description

Specifies that a case is excluded from the graph if the case is missing a value for any of the variables actually used in the graph. For example, if variables x, y, and z are used in the graph, a case is excluded only if it is missing a value for one of these variables. The missingness of other variables is not considered. missing.pairwise is the default behavior for handling missing values.
