Xcalibre 4: User-Friendly Item Response Theory
Xcalibre 4 is a revolutionary system to perform item response theory (IRT) analyses through a user-friendly interface (no command code), producing automatically built narrative reports with embedded tables and graphics. Tired of seeing tables of ASCII text from the 1980s and having to write code just to see some graphs – only to then have to spend hours copy-and-pasting into Word? Xcalibre replaced that entire process. More information is available here.
