R/prob_detect_single_grab.R
prob_detect_single_grab.Rd
This function calculates the probability of detection in a single grab sample comprising of r
primary increments for given serial correlation d
.
prob_detect_single_grab(r, p, d)
number of primary increments in a grab sample or grab sample size
limiting fraction or proportion of contaminated increments
serial correlation of contamination between the primary increments
Probability of detection in a grab sample
The probability of detection in any of the grab sample is given by \(p_d\) as $$p_d = 1-(1-p)(1-p(1-d))^{r-1}$$
r <- 25
p <- 0.005
d <- 0.99
