But, I am confused over the algo used for inner model analysis, to whether use linear or warp. Could you point me out to any of your tutorials where you may have discussed this with some examples.

Can WarpPLS handle binary (yes/now) single item variables like in the model above? I saw that SmartPLS cannot handle binary variables. <br />2. The link from independent to mediating variable is Sig, and the one from mediating variable to dependent also sig. However, the indirect effect is non-sig.

Some of its features, such as the ability to conduct a factor-based SEM and model nonlinear relationships, are, to the best of my knowledge, unique among SEM software.<br /><br />--------------<br /><br />WarpPLS has been used to study a number of topics in a variety of disciplines and fields, including: accounting, anthropology, clinical psychology, ecology, economics, education, global environmental change, epidemiology, evolutionary psychology, exercise physiology, information systems, international business, finance, management, marketing, medicine, nursing, organizational psychology, and sociology. Articles presenting empirical studies employing WarpPLS as the main data analysis tool have been published in journals that are highly ranked in their respective fields, such as: Global Environmental Change, Journal of Advanced Nursing, Journal of Management Information Systems, International Business Review, Journal of the Association for Information Systems, Decision Support Systems, and Management Information Systems Quarterly.[3]<br /><br />Main features<br />Among the main features of WarpPLS is its ability to identify and model non-linearity among variables in path models, whether these variables are measured as latent variables or not, yielding parameters that take the corresponding underlying heterogeneity into consideration.[4][5] This and other notable features are summarized through the list below.<br /><br />Guides SEM analysis flow via a step-by-step user interface guide.[6]<br />Implements classic (composite-based) as well as factor-based PLS algorithms.<br />Identifies nonlinear relationships, and estimates path coefficients accordingly.<br />Also models linear relationships, using classic and factor-based PLS algorithms.<br />Models reflective and formative variables, as well as moderating effects.<br />Calculates P values, model fit and quality indices, and full collinearity coefficients.<br />Calculates effect sizes and Q-squared predictive validity coefficients.<br />Calculates indirect effects for paths with 2, 3 etc. segments; as well as total effects.<br />Calculates several causality assessment coefficients.<br />Provides zoomed 2D graphs and 3D graphs.<br /><br />References<br /> Kock, N., & Mayfield, M.
