ScreeningStep {ScreenClean} | R Documentation |
ScreeningStep performs the cleaning step of the graphlet screening
ScreeningStep(y.tilde, gram, cg.all, nm, v, r, q0 = 0.1, scale = 1)
y.tilde |
|
gram |
the regularized gram matrix |
cg.all |
a list whose kth element is a matrix of k columns. Its rows contain all the connected subgraph with k nodes. |
nm |
the maximal subgraph invesgated in the screening step |
v |
an essential tuning parameter of graphlet screening, tied to the sparse level |
r |
an essential tuning parameter of graphlet screening, tied to the signal strength |
q0 |
the minimal screening parameter |
scale |
|
survivor |
A logical vector, where TRUE means retained as a protential signal. |
When nm=1, it is just univariate threholding, and thurs the screening step of UPS.
