correlation_grab: Serial correlation between grab samples
Description
This function calculates the resulting serial correlation between grab samples each having r primary increments with original serial correlation d.
Usage
correlation_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
Value
Serial correlation between grab samples
Details
The serial correlation between blocks (grab samples) is given by \(d_g\) as
$$d_g = [dp(1-p(1-d))^{r-1}]/p_d$$
where \(p_d\) is the probability of detection in any of the block (grab sample) which is calculated by using prob_detect_single_grab.
