Welcome to Q*Power!
Q*Power is a free, web-based program to aid in the process of designing diagnostic tests. The user enters expected test and attribute specifications into the program using the form below. Then, the program runs a simulation study to predict how accurately and reliably a diagnostic classification model can be expected to provide the diagnoses for the attributes measured by your test. Detailed instructions for using the program, as well as technical aspects of the analyses run by the program, can be found in the Q*Power User's Guide.
Q*Power is in beta. Please feel free to begin using Q*Power, but be patient with us as we continue to refine the program's features and functionality.
