Background After conducting necessary condition analysis (NCA), researchers have concluded that a certain, not too low, level of well-being is necessary but not sufficient for a high level of

When predictors of outcomes are necessary: guidelines for the combined use of PLS-SEM and NCA

This research introduces the combined use of partial least squares–structural equation modeling (PLS-SEM) and necessary condition analysis (NCA) that enables researchers to explore and validate

Levels of necessity of entrepreneurial ecosystems elements

Knowing What We Know about IT and Business Value: Cause for Concern about Endogeneity Problems and Potential Solutions

A relatively little-known category of explicitly causal case study research methods that originated in sociology and political science are described, shows how they address endogeneity problems, and explores how they might complement statistical methods in the study of IT business value.

The Relationship Between Intelligence and Creativity: On Methodology for Necessity and Sufficiency
