cutoff,omics_network-method: Choose the best cutoff

Description

Allows estimating the best cutoff. For a sequence of cutoff, the p value corresponding to each cutoff value of the sequence. Mainly recommended for single time cascade networks. To achieve more sparsity in other settings, please use a fiiting function based on the stability selection or selectboost algorithms.

Usage

# S4 method for omics_network
cutoff(Omega, sequence = NULL, x_min = 0)

Value

A list containing two objects :

p.value

the p values corresponding to the sequence of cutoff

p.value.inter

the smoothed p value vector, using the loess function

Arguments

Omega

a omics_network object

sequence

a vector corresponding to the sequence of cutoffs that will be tested.

x_min

an integer ; only values over x_min are further retained for performing the test.
