Using matrix algebra, we can decompose the covariances of multitrait-multimethod (MTMM) manifest variables into the parameters in the model. The covariance matrix, Σ, for the trait-method units, Ytm (i.e., the manifest variables) is the expected value of the second central moment YtmY ′ tm, and gives rise to the covariance structure model, Σ = ΛtΨtΛt + ΛmΨmΛm + Θ We can also express the covariance structure model in a traditional factor analytic way,
