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

The goal of QTEST 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 supercial 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.

In order to use QTEST you will need both an MCR installer and a compiled version of the QTEST 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 on all platforms. Second, download a compiled version of QTEST. Whenever you would like to start a new instance of QTEST, simply open this QTEST file. For a Windows installation, choose the same bit size for both the MCR installer and QTEST. This bit size matches the computer bit size on which QTEST will be installed.
