Project Activities
In this project, researchers will develop a general method to enable the specification of models including structural equation models and multilevel models as well missing data mechanisms and non-normality of data through drawing path diagrams. The researchers will then develop methods for simulating data based on those models and methods for calculating statistical power based on repeated simulations, with the resulting methods being robust to non-normal data and missing data. Researchers will also develop software called MCpower to conduct power analysis via the proposed framework. MCpower will run as a web application and can be used locally on a personal computer or remotely on a Web server within a web browser. The project is expected to offer the community of education researchers an easy-to-use and general-purpose tool to conduct sophisticated statistical power analysis for structural equation and multilevel models with non-normal and missing data.
