GSCA in SmartPLS
Generalized Structured Component Analysis, Simplified. Composite modeling without complexity.
Overview
GSCA (Generalized Structured Component Analysis) extends composite‑based modeling beyond classic PLS. In SmartPLS, GSCA integrates seamlessly with your constructs, indicators, and paths.
Why It Matters
- Component realism: ideal when constructs are formative/composite.
- Small‑sample size: stable results with limited N.
- Unified environment: compare GSCA with PLS‑SEM and CB‑SEM side by side.
How It Works in SmartPLS
- Select GSCA as the estimator for composite models.
- Obtain path coefficients, weights, communalities, redundancies, and fit criteria.
- Use bootstrap for inference testing
- Moderation, mediation, moderated-mediation, conditional process analysis
Use Cases
- Marketing/IS composite constructs (e.g., service quality, capabilities).
- Formative indicator structures and index‑like constructs.
- Model comparison with PLS‑SEM and CB‑SEM to validate theory.
