Plot Normalized Eigenvalues of the Influence Matrix

Produces panel (a) of the diagnostic figure: the normalized eigenvalues of the influence matrix, with horizontal reference thresholds for \(q = 1, \ldots, 7\).

Usage

plot_normalized_eigenvalues(diag, pch = 16, cex = 1, main = "")

Arguments

diag

A list returned by cnc_diagnostics.

pch

Plotting character (default 16).

cex

Point size expansion (default 1).

main

Plot title (default empty).

Value

Called for its side effect (a base-graphics plot). Returns NULL invisibly.

Examples

data(itajai)
fit <- evbsreg.fit(cbind(1, itajai$pressure), itajai$wind)
diag <- cnc_diagnostics(fit)
plot_normalized_eigenvalues(diag, main = "(a)")
