Why Identification Matters in SEM Structural Equation Modeling (SEM) is one of the most powerful tools in quantitative research. It allows scholars to test complex theories, measure latent constructs, and model mediation or moderation effects. Researchers often call SEM the “gold standard” of statistical modeling. However, a hidden truth is often ignored: SEM collapses without … Read more
In qualitative research, validity is not merely technical — it is deeply interpretive, ethical, and relational. Yet, while researchers meticulously detail methods, tools, and coding frameworks, they often gloss over or omit a critical component: positionality and reflexivity. This oversight undermines not only the credibility of the study but also its epistemological integrity. At Research … Read more
Time-series models are among the most powerful tools in empirical research — used to forecast trends, evaluate policy impacts, and assess long-term relationships across economics, finance, climate, and public policy. But too often, researchers focus on sophisticated modeling techniques (like ARDL, VAR, or VECM) without laying the proper statistical foundation.The result? Spurious regressions, invalid inferences, … Read more
Regression analysis is one of the most widely used statistical tools in empirical research. Yet, beneath many published models lies a silent killer of validity: the misuse of control variables. Too often, researchers include controls reflexively — without a clear understanding of their role in causal inference or model integrity. This article dives into what … Read more
