id_adj {fullROC} | R Documentation |
Simple adjustment
Description
A function to adjust the id rates for ca lineups using the 1/(lineup size) method; is applicable to ordered id rates with the same confidence levels for all responses.
Usage
id_adj(rate, lsize = 6, csize = 3)
Arguments
rate |
ID rate vector. |
lsize |
Lineup size. Defaults to 6. |
csize |
Number of confidence levels. Defaults to 3. |
Value
Adjusted ID vector.
Examples
ca_id <- c(rep(0,3), rep(c(0.1, 0.15, 0.25), 2))
id_adj(ca_id)
## change line size to 5
id_adj(ca_id, lsize = 5)
## For multiple groups
ca_id2 <- c(c(rep(0,3), rep(c(0.1, 0.15, 0.25), 2)),
c(rep(0,3), rep(c(0.1, 0.2, 0.3), 2)) )
group <- rep(c("a", "b"), each = 9)
## Adjust id rates by groups
by(ca_id2, group, id_adj)
