Discriminant validity assessment has become a generally accepted prerequisite for analyzing relationships between latent variables. For variance-based structural equation modeling, such as partial least squares, the FornellLarcker criterion and the examination of cross-loadings are the dominant approaches for evaluating discriminant validity. By means of a(More)
Application developers are of growing importance to ensure that software platforms (e.g. Facebook, Android) gain or maintain a competitive edge. However, despite calls for research to investigate developers’ perspective on platform-centric ecosystems, no research study has been dedicated to identifying the facets that constitute developers’ perception of(More)
When applying multivariate analysis techniques in information systems and social science disciplines, such as management information systems (MIS) and marketing, the assumption that the empirical data originate from a single homogeneous population is often unrealistic. When applying a causal modeling approach, such as partial least squares (PLS) path(More)
While the question how community design influences user behaviors in online communities has recently attracted considerable research, few studies empirically evaluate the influencing factors of specific user behaviors. Building on Ren et al.’s (2007) conceptual framework of identity-based vs. bond-based attachment in online communities, this study evaluates(More)
This article addresses Rönkkö and Evermann’s criticisms of the partial least squares (PLS) approach to structural equation modeling. We contend that the alleged shortcomings of PLS are not due to problems with the technique, but instead to three problems with Rönkkö and Evermann’s study: (a) the adherence to the common factor model, (b) a very limited(More)
