Robustness Checks using

Описание: In this video titled: Robustness Checks using #SmartPLS4, we will discuss how to perform structural model robustness checks that includes the assessment of Linearity, Endogeneity, and Heterogeneity.

The session is divided into three main sections, each addressing a crucial aspect of model assessment.

Linearity Assessment:
Learn how to check the assumption of linearity in Structural Equation Modeling (SEM) models. Understand the use of quadratic effects in SmartPLS, interpret P values, and confirm the linearity of relationships between variables.

Endogeneity Analysis:
Explore the assessment of endogeneity in your model using the Gaussian Copula approach. Follow a step-by-step guide to checking individual and combined relationships for endogeneity issues.

Heterogeneity Examination:
Gain insights into the significance of unobserved heterogeneity and its impact on model estimates. Discover the FIMIX procedure in SmartPLS for assessing heterogeneity. Understand the process of determining the optimal number of segments and interpreting model selection criteria.

By the end of this session, you'll be equipped with valuable knowledge and practical techniques to ensure the robustness of your structural model in SmartPLS4, covering linearity, endogeneity, and unobserved heterogeneity.
