Module 3: Building a Regression Model
Purpose
This module teaches how to draw a regression model in SmartPLS 4 and specify the dependent variable, predictors, controls, and intercept.
Learning Objectives
After this module, learners should be able to:
- Create a graphical regression model.
- Add a dependent variable and independent variables.
- Add controls.
- Include or remove the intercept intentionally.
- Save a clean model for reporting.
Example Model
Research question:
Which factors predict student satisfaction with a digital learning platform?
Dependent variable:
SATISFACTION
Predictors:
USEFULNESS
EASE_OF_USE
TRUST
SERVICE_QUALITY
Controls:
AGE
EXPERIENCE
GENDER_MALE
SmartPLS Steps
- Create a new project.
- Import the dataset.
- Create a new model.
- Add the dependent variable.
- Add independent variables.
- Draw arrows from predictors to the dependent variable.
- Keep the intercept unless your research design requires removing it.
- Save the model with a clear name.
Intercept Rule
For most regression models, keep the intercept. Removing it changes the meaning of coefficients and is rarely appropriate unless theory and design justify a zero-intercept model.
Model Documentation
Record:
- Model name
- Dataset name
- Dependent variable
- Predictors
- Controls
- Whether intercept is included
- SmartPLS version
Practice
Create two models:
- Simple model:
SATISFACTION <- USEFULNESS - Multiple model:
SATISFACTION <- USEFULNESS + EASE_OF_USE + TRUST + SERVICE_QUALITY + AGE + EXPERIENCE
