Structural Equation Modeling (PLS-SEM & CB-SEM)

Simultaneous estimation of measurement and structural models, mediation, moderation, MGA, and higher-order constructs.

Structural Equation Modeling is the gold standard for multi-construct survey research. We execute both variance-based (PLS-SEM in SmartPLS) and covariance-based (CB-SEM in AMOS, LISREL, R lavaan) approaches to meet top-tier journal standards.

SmartPLS Standard

Partial Least Squares SEM (PLS-SEM)

Ideal for complex models, reflective/formative constructs, and non-normal data; includes 5,000-sample bootstrapping, blindfolding (Q²), PLSpredict, and IPMA.

Required Data & Inputs

Raw questionnaire data, item-to-construct mapping, and conceptual model diagram.

Dedicated Software
SmartPLSR (seminr / cSEM)WarpPLS
What You Receive (Deliverables)

Outer model (loadings, alpha, CR, AVE, Fornell-Larcker, HTMT) and inner model (path betas, t-values, R², f², Q², SRMR) plus high-res model diagrams.

Theory Confirmation

Covariance-Based SEM (CB-SEM in AMOS, LISREL & R lavaan)

Theory testing via maximum likelihood covariance estimation, model respecification using modification indices, and comprehensive goodness-of-fit evaluation.

Required Data & Inputs

Survey dataset (typically N > 200) and theoretical model specification.

Dedicated Software
AMOSLISRELR (lavaan)Mplus
What You Receive (Deliverables)

Full fit indices table (χ²/df, RMSEA, CFI, TLI, NFI, SRMR), regression weights, and standardized/unstandardized path diagrams.

Advanced Effects

Mediation, Moderation, Conditional Process (Hayes) & Multi-Group (MGA)

Serial/parallel mediation, continuous/categorical moderation, Sobel & bootstrap CI tests, VAF calculation, and Multi-Group Analysis (MGA) with MICOM invariance.

Required Data & Inputs

Data for main constructs, mediators, moderators, or grouping variables.

Dedicated Software
SmartPLSSPSS PROCESS Macro (Hayes)AMOSR
What You Receive (Deliverables)

Direct/indirect/total effects table, bias-corrected bootstrap CIs, interaction simple-slope plots, and MGA permutation p-values.
