Deliberate Q

Deliberate Q is a visualisation tool for Q Methodology analysis. It is a java swing application with these features:

• Principal Components Analysis
• Centroid Method
• Factor rotations manually or using standard algorithms (Varimax, Orthomax etc)
• Rotation graphs
• Animated intersubjective correlation graphs for visualisation of multi stage data
• Venn Diagram views for factor interpretation

Getting started

Download the latest release jar from Releases and run it as below:

java -jar deliberate-q-2.1-jar-with-dependencies.jar

Build instructions

You need to have Java (Oracle or OpenJDK) and Maven 3+ installed.

To build the jar with all dependencies included:

mvn clean install

This writes the jar file to the target directory and you can run the application like this (from that directory):

java -jar deliberate-q-2.0.8-jar-with-dependencies.jar

Or to compile the source, run the unit tests and then run the application from the command line using maven:

mvn test exec:java

How to release a new version

For project administrators, to build a release (tagged in git source control) on Linux/Unix:

./release.sh VERSION_HERE

Mathematics libraries

T distribution routines from apache commons-math are used in the calculation of factor scores.

Jama is used for eigenvalue decomposition in Principal Components Analysis.
