## Structural Equation Modeling in R Tutorial 8: Introduction to Stacked Models and Factorial Measurement Invariance Testing

Table of Contents Data Input Stacked Models in Lavaan Model Comparison Using lavaan Made for Jonathan Butner’s Structural Equation Modeling Class, Fall 2017, University of Utah. This handout will focus on implementing stacked models in lavaan, which allow us to test a model for two different groups (for example, control vs. intervention). This syntax imports the X variable, 192 person dataset called HW9 2017.

## Structural Equation Modeling in R Tutorial 7: Full Structural Equation Modeling

Table of Contents Data Input Structural Equation Modeling Using lavaan: Measurement Model Structural Equation Modeling Using lavaan: Full Model Model Comparison Using lavaan Interpreting and Writing Up Your Model Made for Jonathan Butner’s Structural Equation Modeling Class, Fall 2017, University of Utah. This handout begins by showing how to import a matrix into R. Then, we will overview how to establish a measurement model in R using the lavaan package.

## Structural Equation Modeling in R Tutorial 6: Confirmatory Factor Analysis using lavaan in R

Table of Contents Data Input Confirmatory Factor Analysis Using lavaan: Factor variance identification Model Comparison Using lavaan Calculating Cronbach’s Alpha Using psych Made for Jonathan Butner’s Structural Equation Modeling Class, Fall 2017, University of Utah. This handout begins by showing how to import a matrix into R. Then, we will overview how to complete a confirmatory factor analysis in R using the lavaan package.
