JTRCI: Jacobson & Truax reliable change indices
A newer version of this package is available at github.com/AWKruijt/JT-RCI (notice the added hyphen).
I strongly advise switching to JT-RCI for any new projects. This current version is kept online because I know that manuscripts using it in their (shared) syntax are currently under review. In time the old JTRCI version will be removed from github.
In this old version (@ awkruijt/JTRCI) the higherisbetter option does not work correctly when type = "JT" (does work for type = "RCI") - the new version (awkruijt/JT-RCI) fixes this and is generally more streamlined.
When switching, it is good to know that in the new version the following parameter names have changed:
JT.crit -> JTcrit
type -> indextype
norm.M -> normM
norm.SD -> normSD
