Novel Statistical Approaches and Tools

The Research Methods and Statistics Lab also works to create novel statistical methods and evaluate the performance of new techniques. This work involves method creation and simulation studies under a variety of conditions to study characteristics like power and Type I error control of the new statistical procedure.

Current Projects:

​

• Issues in Testing Configural Invariance with Unequal Group Sample Sizes

​

• Equivalence tests for Linear and Logistic Regression
