nem.jackknife: Jackknife for nested effect models

In cbg-ethz/pcNEM: Probabilistic combinatorial nested effects model

Description

Assesses the statistical stability of a network via a jackknife procedure: Each S-gene is left out once and the network reconstructed on the remaining ones. The relative frequency of each edge to appear in n-1 jackknife samples is returned.

Usage

nem.jackknife(D, thresh=0.5, inference="nem.greedy",models=NULL,control=set.default.parameters(unique(colnames(D))), verbose=TRUE)

## S3 method for class 'nem.jackknife'
print(x, ...)

Arguments

D	data matrix with experiments in the columns (binary or continious)
thresh	only edges appearing with a higher frequency than "thresh" are returned
inference	search to use exhaustive enumeration, triples for triple-based inference, pairwise for the pairwise heuristic, ModuleNetwork for the module based inference, nem.greedy for greedy hillclimbing, nem.greedyMAP for alternating MAP optimization using log odds or log p-value densities
models	a list of adjacency matrices for model search. If NULL, an exhaustive enumeration of all possible models is performed.
control	list of parameters: see set.default.parameters
verbose	do you want to see progression statements? Default: TRUE
x	nem object
...	other arguments to pass

Details

Calls nem or nemModelSelection internally, depending on whether or not parameter lambda is a vector and parameter Pm != NULL.

Value

nem object with edge weights being the jackknife probabilities
