CleaningStep {ScreenClean}

GC-step of the graphlet screening

Description

CleaningStep performs the cleaning step of the graphlet screening

Usage

CleaningStep(survivor, y.tilde, gram, lambda, uu)

Arguments

survivor

the result of the screening step, a logical vector.

y.tilde

X'y, where X and y are the predictor matrix and the reponse vector.

gram

the thresholded sparse gram matrix

lambda

the tuning parameters of the cleaning step, whose optimal choice is tied to the sparse level.

uu

the tuning parameter of the cleaning step; its optimal choice has the intuition of the detected minimal signal strength.

Value

beta.gs

the estimated regression coefficient of the graphlet screening, a numeric vector
