Negative exponential dispersal kernel to calculate the probability of dispersal between two nodes. Used in probabilistic indexes (e.g., PC, BCPC, ProtConn etc.)
probability_distance( probability, median_distance, eval_distance = NULL, min.prob = 0.01 )
probability | numeric. Probability of dispersal at median_distance. If NULL |
---|---|
median_distance | numeric. Up to five maximum dispersal distance (km) |
eval_distance | numeric. Calculate the probability of dispersal at a specific median distances (km). Available when only one median_distance is used. |
min.prob | numeric. Value between 0-1, maximum x axe value |
if (FALSE) { probability_distance(probability= 0.5, median_distance = c(1, 10, 30, 100), min.prob = 0.01) probability_distance(probability= 0.5, median_distance = 100, eval_distance = 100) probability_distance(probability= 0, median_distance = 100, eval_distance = 1) }
