Description

Highest Density Regions

Usage

interval_hdr(x, y, ...)
# S4 method for numeric,numeric
interval_hdr(x, y, level = 0.954)
# S4 method for numeric,missing
interval_hdr(x, level = 0.954, ...)

Value

A three-columns numeric

matrix giving the lower and upper boundaries of the HPD interval and associated probabilities.

Arguments

x

A numeric vector giving the coordinates of the points where the density is estimated.

y
