WebFactor analysis is a 100-year-old family of techniques used to identify the structure/dimensionality of observed data and reveal the underlying constructs that give rise to observed phenomena. The techniques identify and examine clusters of inter-correlated variables; these clusters are called “factors” or “latent variables” (see Figure 1).
