Analysis of Commonality

Analysis of Commonality:

Analysis of commonality is a method for causal modeling . In a simple case of two independent variables x₁ and x₂ , for example, analysis of commonality posits three sources of causation, described by three latent variables: u₁ and u₂ , which reflect the unique contributions of x₁ and x₂ respectively, and c₁₂ – the contribution from the sources common to x₁ and x₂ .

In other words, analysis of commonality in this example pretends to partition the variance of the dependent variable explained by independent variables x₁ and x₂ into independent contributions from latent variables u₁, u₂, c₁₂ .
