prob_detect_single_grab: Probability of detection in a single grab sample

In grabsampling: Probability of Detection for Grab Sample Selection

Description

This function calculates the probability of detection in a single grab sample comprising of r primary increments for given serial correlation d.

Usage

prob_detect_single_grab(r, p, d)

Arguments

r	number of primary increments in a grab sample or grab sample size
p	limiting fraction or proportion of contaminated increments
d	serial correlation of contamination between the primary increments

Details

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}

Value

Probability of detection in a grab sample

Examples

   r <-  25
   p <-  0.005
   d <-  0.99
   prob_detect_single_grab(r, p, d)
