In jewel: Graphical Models Estimation from Multiple Sources

Evaluation of graph estimation method's performance if the true graph is known.

Description

Function compares adjacency matrices of the true and estimated simple graphs and calculates the number of true positives (correctly estimated edges), true negatives (correctly estimated absence of edges), false positives (edges present in the estimator but not in the true graph) and false negatives (failure to identify an edge).

Usage

evaluatePerformance(G, G_hat)

Arguments

G	true graph's adjacency matrix.
G_hat	estimated graph's adjacency matrix. Must have the same dimensions as G.

Value

performance - a numeric vector of length 4 with TP, TN, FP, FN.

Examples

{
K <- 3
p <- 50
n <- 20
data <- generateData_rewire(K = K, p = p, n = n, ncores = 1, verbose = FALSE)
G_common_true <- data$CommonGraph
X <- data$Data
res <- jewel(X, lambda1 = 0.25)
G_common_est <- res$CommonG
evaluatePerformance(G = G_common_true, G_hat = G_common_est)
}
