WebOct 22, 2010 · Structural equation modeling (SEM) is a set of statistical techniques used to measure and analyze the relationships of observed and latent variables. Similar but more powerful than regression analyses, it examines linear causal relationships among variables, while simultaneously accounting for measurement error. WebSEM sample polishing Grinding removes saw marks and levels and cleans the surface of the specimen. Polishing eliminates the artifacts of grinding but removes very little material. Grinding uses fixed abrasives – the abrasive particles are bonded to the paper or plates – for fast material removal.
