Negative Exponential kernel
Description
Section titled “Description”Negative Exponential kernel
negative_exponential_function(x, mean_dispersal_dist)
Arguments
Section titled “Arguments”x
:<numeric>
distance at which the probability should be calculated.mean_dispersal_dist
:<numeric>
mean dispersal distance. Needs to be (>0).
Details
Section titled “Details”The negative exponential kernel is defined as:
f(x) = {1} / {2 \pi a^2} e^{-{x} / {a}}
where a
is the mean dispersal distance divided by 2.
