selectFast | R Documentation |
Select a graph within the (data-driven) families of graphs EW
, C01
, and LA
.
selectFast(X, dmax=min(floor(nrow(X)/3),nrow(X)-3,ncol(X)-1),
K=2.5, family="EW",
min.ev=10**(-8), max.iter=200, eps=0.01,
beta=nrow(X)*nrow(X)/2, tau=1/sqrt(nrow(X)*(ncol(X)-1)), h=0.001, T0=10,
verbose=FALSE )
