Exponential Growth Model
Description
Density and random generation of an exponential growth model distribution.
Usage
dExponentialGrowth(x, a, b, r, log)
rExponentialGrowth(n, a, b, r)
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. |
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.
