compare-methods {Cascade}

Some basic criteria of comparison between actual and inferred network.

Description

Allows comparison between actual and inferred network.

Usage

## S4 method for signature 'network,network,numeric'
compare(Net, Net_inf, nv = 1)

Arguments

Net

A network object containing the actual network.

Net_inf

A network object containing the inferred network.

nv

A number that indicates at which level of cutoff the comparison should be done.

Value

A vector containing : sensibility, predictive positive value, and the F-score

Methods

list("signature(Net = \"network\", Net_inf = \"network\", nv = \"numeric\")")
