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.
