bootThreshold: Threshold network based on bootstrapped intervals

In SachaEpskamp/bootnet: Bootstrap Methods for Various Network Estimation Routines

Threshold network based on bootstrapped intervals

Description

This function takes the output of bootnet and returns a network as if it had been estimated using estimateNetwork, but with edges removed (set to zero) based on some significance level.

Usage

bootThreshold(bootobject, alpha = 0.05, verbose = TRUE, thresholdIntercepts = FALSE)

Arguments

bootobject	Nonparametric bootstrap results from bootnet
alpha	Significance level
verbose	Logical, should progress be reported to the console?
thresholdIntercepts	Logical, should intercepts also be thresholded?

Value

A bootnetResult object with the following elements:

graph	The weights matrix of the network
intercepts	The intercepts
results	The results of the estimation procedure
labels	A vector with node labels
nNodes	Number of nodes in the network
nPerson	Number of persons in the network
input	Input used, including the result of the default set used

Examples

## Not run: 
# BFI Extraversion data from psychTools package:
library("psychTools")
data(bfi)
bfiSub <- bfi[,1:25]

# Estimate unregularized network:
Network <- estimateNetwork(bfiSub, default = "pcor", corMethod = "cor")

# Bootstrap 1000 values, using 8 cores:
boots <- bootnet(Network, nBoots = 1000, nCores = 8)

# Threshold network:
Network_thresholded <- bootThreshold(boots)

# Plot:
plot(Network_thresholded)

## End(Not run)
