IVD Performance v12.0.jmpaddin
I have posted and updated version of this script to use with JMP12. The categorical platform was by-passed (due to a technical glitch) in favor of the categorical platform for the 2x2 table and graphic which is now a mosaic plot.
The IVD Performance Add-In was designed for quick reporting of diagnostic test results. The output includes the common 2x2 table of results, a frequency chart, as well as the standard performance measures of a diagnostic test and their associated 95% score confidence intervals. The Add-In also supports a "by" variable. The measures include:
PPV (positive predictive value)
NPV (negative predictive value)
Positive likelihood ratio
Negative likelihood ratio
For likelihood ratio confidence intervals are based on the method in Simel, et. al.
