dTrapezoidal: Trapezoidal Distribution

In nimbleCarbon: Bayesian Analyses of Radiocarbon Dates with NIMBLE

Trapezoidal Distribution

Description

Density and random generation of an Trapezoidal distribution.

Usage

dTrapezoidal(x, a, m1, m2, b, log)

rTrapezoidal(n, a, m1, m2, b)

Arguments

x	A calendar year (in BP).
a	lower (earliest) limit of the distribution (in BP).
m1	lower mode (in BP)
m2	upper mode (in BP).
b	upper (latest) limit of the distribution (in BP).
log	TRUE or 1 to return log probability. FALSE or 0 to return probability.
n	number of random draws. Currently only n = 1 is supported, but the argument exists for standardization of "r" functions.
