QTEST 2.1 is a custom-designed public-domain statistical analysis package for order-constrained inference.

The goal of QTEST 2.1 is to make modeling and quantitative testing accessible to behavioral decision researchers interested in substantive questions. We provide a novel, rigorous, yet very general, quantitative diagnostic framework for testing theories of binary choice. This permits the nontechnical scholar to proceed far beyond traditionally rather superficial methods of analysis, and it permits the quantitatively savvy scholar to triage theoretical proposals before investing effort into complex and specialized quantitative analyses. Our theoretical framework links static algebraic decision theory with observed variability in behavioral binary choice data.

QTEST 2.1 Software

In order to use QTEST 2.1 you will need both an MCR installer and a compiled version of the QTEST 2.1 software program, both of which can be found below. First, download and install the MCR installer. The MCR installer only needs to be installed once on your computer and it must be installed for all platforms. Second, download a compiled version of QTEST 2.1. Whenever you would like to start a new instance of QTEST 2.1, simply open this QTEST 2.1 file.
