Test for conditional independence in the multivariate normal distribution.
A list with elements
set can be 1) a vector or 2) a right-hand sided formula in
which variables are separated by '+'. In either case, it is tested if
the first two variables in the
set are conditionally
independent given the remaining variables in
(Notice an abuse of the '+' operator in the right-hand sided formula:
The order of the variables does matter.)
NULL then it is tested whether the first two
variables are conditionally independent given the remaining variables.
x must be a list with components
such as returned by calling
cov.wt( , method='ML') on a dataframe.
An object of class 'citest' (which is a list).
