plot.threshold function

Plotting the thresholding procedure

Plotting method for S3 objects of class threshold. Produces a plot visualising three diagnostics for the thresholding procedure, with threshold values t_k (x axis) against (i) Ratio_k, the ratio of the number of non-zero to zero entries in the matrix, as the threshold varies (ii) Diff_k, the first difference of Ratio_k

(iii) |CUSUM_k|, the absolute scaled cumulative sums of Diff_k

## S3 method for class 'threshold'
plot(x, plots = c(TRUE, FALSE, TRUE), ...)

Arguments

• x: threshold object
• plots: logical vector, which plots to use (Ratio, Diff, CUSUM respectively)
• ...: additional arguments

Returns

A network plot produced as per the input arguments

Details

Examples

## Not run:

library(fnets)
out <- fnets(data.unrestricted,
   var.args = list(n.cores = 2)
)
# Granger-causal network
th1 <- threshold(out$idio.var$beta)
plot(th1)
print(th1)
# Partial correlations
th2 <- threshold(out$lrpc$pc)
# Long-run partial correlations
th3 <- threshold(out$lrpc$lrpc)
## End(Not run)
