Edgewise Linear Model

Description

This function computes the specified linear model (LM) for each edge in the network, and calculates the multiple testing p-value based on the p.adjust function.

Usage

edge_lm(net, nnodes, idata, mod, diag = FALSE, padj,
       cores = NULL, expList = NULL, verbose = TRUE,
       ...)

Arguments

net

3D volume (2D matrices for each observation) or 2D matrix of edges as columns.

nnodes

Number of network nodes.

idata

Matrix or data.frame including independent variables of interest of the model.

mod

Model, specify as a string, e.g., "~Group + Age".

diag

Logical indicating if matrix diagonal is to be included in the analysis (default: FALSE).

padj

Character string that indicates the p.adjust method.

cores

Number of selected cores for parallel computing (default: NULL).

expList

Character string adding variable names to the varlist of 'clusterExport' (default: NULL).

verbose

Logical indicating if messages should be printed (default: TRUE).

...

Additional arguments to be passed to the low level 'lm' function.

Details

It's VERY IMPORTANT when giving net as a 2D matrix or data.frame, to be completely sure that column distribution fits that of the upper triangle indices of an nnodes * nnodes matrix. This may be verified through the edge indices, e.g., "which(upper.tri(matrix(nrow = nnodes, ncol = nnodes)), arr.ind = T)" (see vignette NBR-LME for more details).

To know more about padj methods, check help for the p.adjust function. It is noticeable that this multiple comparison approach can be much more faster than the permutations run by the Network-Based Statistics framework, however this is a much more conservative approach (see Zalesky et al. (2010) doi: 10.1016/j.neuroimage.2010.06.041 for more detail).

Value

data.frame containing the edge labels, observed statistics, their corresponding p-value, and their adjusted p-values.

Examples

data(frontal2D)

edge_result <- edge_lm(net = frontal2D[,-(1:3)], nnodes = 28,
  idata = frontal2D[,1:3], mod = "~ Group + Sex * Age",
  padj = "fdr")
head(edge_result)
if(any(edge_result[,5]<0.05)){
  show(edge_result[which(edge_result[,5]<0.05),1:5])
}

Details

Data was taken from the ADHD200 dataset and variables were manipulated in order to be different of the original data. Functional connectivity was measured as the Pearson correlation between the average fMRI signal from the regions of interest (ROI), i.e., 28 anatomical areas of the frontal lobe. Thus, a total of 378 pairwise connections are contained in the dataset.

Network-based R-statistics using Linear Model

Description

This function computes the specified linear model (LM) for each edge in the network, and calculates the family wise error (FWE) p-value for the size of the clusters of connected edges that are individually below the P threshold (thrP), or above the T threshold (thrT). FWE estimation is based on the null distribution of the maximum size of sets of connected edges (defined as above), obtained with nperm permutations of the original data.

Usage

nbr_lm(net, nnodes, idata, mod, 
       alternative = c("two.sided", "lower", "greater"),
       diag = FALSE, nperm, thrP = 0.05, thrT = NULL,
       cores = NULL, nudist = FALSE, expList = NULL, verbose = TRUE,
       ...)

Arguments

net

3D volume (2D matrices for each observation) or 2D matrix of edges as columns.

nnodes

Number of network nodes.

idata

Matrix or data.frame including independent variables of interest of the model.

mod

Model, specify as a string, e.g., "~Group + Age".

alternative

a character string specifying the alternative hypothesis, must be one of "two.sided" (default), "greater" or "lower". You can specify just the initial letter.

diag

Logical indicating if matrix diagonal is to be included in the analysis (default: FALSE).

nperm

Number of permutations.

thrP

Individual edge p-value threshold (if NULL, thrT should be given).

thrT

Individual edge T-value threshold (if NULL, thrP should be given).

cores

Number of selected cores for parallel computing (default: NULL).

nudist

Logical indicating if null distribution should be returned (default: FALSE).

expList

Character string adding variable names to the varlist of 'clusterExport' (default: NULL).

verbose

Logical indicating if messages should be printed (default: TRUE).

...

Additional arguments to be passed to the low level 'lm' function.

Details

Regarding nperm, I suggest first setting it to small values (5 or 10) in order to test that everything runs fine. After that, set nperm to 1000 or larger number to decrease the margin of error of the FWE p-value (see https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/Randomise/Theory#Conditional_Monte_Carlo_Permutation_Tests to explore the behavior of FWE p-value as a function of nperm).

Value

List containing the observed statistics and their corresponding FWE p-values, if requested by nudist it will return the null distribution.

Observed statistics for every individual edge: corresponding subset of connected nodes and strength for each model term.
FWE for components: binary and strength sum, with their corresponding FWE p-value.
Null Distribution: maximal component size and strength for each permutation. Only returned if nudist is TRUE.

Examples

data(frontal2D)

nbr_result <- nbr_lm(net = frontal2D[,-(1:3)], nnodes = 28,
  idata = frontal2D[,1:3], mod = "~ Group + Sex * Age",
  thrP = NULL, thrT = 4, nperm = 5)
show(nbr_result)

Network-based R-statistics using Mixed Effects Models

Description
