NCA Software

The NCA software is free software that can be used with the free programming language R. 

======VERSION 3.0.1 NOW AVAILABLE======

A Quick Start Guide is available, and also a demonstration of conducting NCA in three steps.

The new version includes a statistical significance test for NCA.

A novice user without knowledge of R or NCA can install the software on the user’s computer and perform an NCA analysis within 15 minutes. 

The software draws ceiling lines and produces several NCA parameters (including necessity effect size) to interpret the results.

An example is shown here.
