flat: The Improper Uniform Distribution

Description

Improper flat distribution for use as a prior distribution in BUGS models

Usage

dflat(x, log = FALSE)
rflat(n = 1)
dhalfflat(x, log = FALSE)
rhalfflat(n = 1)

Arguments

x

vector of values.

log

logical; if TRUE, probability density is returned on the log scale.

n

number of observations.

Value

dflat gives the pseudo-density value of 1, while rflat and rhalfflat return NaN, since one cannot simulate from an improper distribution. Similarly, dhalfflat gives a pseudo-density value of 1 when x is non-negative.
