This is a collection of R scripts that calculate confidence intervals around d-prime using various methods. I occasionally get requests for this code - hence the GitHub repository.
The contents of the repository are as follows:
R code
dprime.R : calculate d'
G.int.R : calculate confidence intervals using Gourevitch & Galanter's (1967) approximation
dprime.pmf.R : compute the sampling distribution of a specific d'
pmf.int.R : calculate confidence intervals using Miller's (1996) method
MLE.int.R : calculate confidence intervals using Maximum Likelihood Estimation
