%description
In order to achieve accurate estimation without sparsity assumption on the
precision matrix, element-wise inference on the precision matrix, and
joint estimation of multiple Gaussian graphical models, a novel method is
proposed and efficient algorithm is implemented. FLAG() is the main
function given a data matrix, and FlagOneEdge() will be used when one pair
of random variables are interested where their indices should be given.
