#### Computer Packages

Charles Metz and colleagues from the Department at Radiology, University of Chicago have created a computer program which does Maximum Likelihood Estimates of ROC data. A web interface for ROCFIT is available.

Version 9 and above contain an ROC graph module. ROC analyses can be computed for non-parametric and bi-negative exponential models. The normal distribution model is not offered.

Although this program does not have a signal detection module, *per se*, it does have built-in statistics functions convenient for working with regression (TREND, SLOPE, and INTERCEPT) and converting *p* and *z* values (NORMSDIST, and NORMSINV).
