Description Usage Arguments Value References See Also Examples
This function computes the matrix of simultaneous p-values for SIN model selection for acyclic directed graphs (DAGs). SIN assumes that a total ordering of the variables is available (e.g., as a time-order).
1 |
order |
a list of pairwise different integers amongst 1,…,p where p is the number of variables. This list specifies a total ordering of the variables by the convention that a list element is smaller than succeeding list elements. |
S |
a covariance or correlation matrix. |
n |
the sample size. |
holm |
Boolean variable indicating whether Holm's p-value adjustment should be used (holm=TRUE) or not (holm=FALSE). |
A matrix of simultaneous p-values with NA
on the diagonal.
