Density and random generation of an exponential growth model distribution.
Usage
dExponentialGrowth(x, a, b, r, log)
rExponentialGrowth(n, a, b, r)
Value
For dExponentialGrowth: the probability (or likelihood) or log probability of an observed date x (in Cal BP). For rExponentialGrowth a simulated date in Cal BP.
Arguments
x
vector of calendar years (in BP).
a
lower (earliest) limit of the distribution (in BP).
b
upper (latest) limit of the distribution (in BP).
r
intrinsic growth rate.
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.
