CHAPTER 18GAMMAThe gamma matrix contains the regression coefficients for theregressions of continuous latent variables on observed independentvariables. The rows represent the continuous latent variables in themodel. The columns represent the observed independent variables in themodel.PSIThe psi matrix contains the variances and covariances of the continuouslatent variables. Both the rows and columns represent the continuouslatent variables in the model.DELTADelta is a vector that contains scaling information for the observeddependent variables.ARRAYS FOR THE MIXTURE PART OF THE MODELALPHA (C)The alpha (c) vector contains the mean or intercept of the categoricallatent variables.LAMBDA (U)The lambda (u) matrix contains the intercepts of the binary observedvariables that are influenced by the categorical latent variables. Therows of lambda (u) represent the binary observed variables in the model.The columns of lambda (u) represent the classes of the categorical latentvariables in the model.TAU (U)The tau (u) vector contains the thresholds of the categorical observedvariables that are influenced by the categorical latent variables. Theelements are in the order of thresholds within variables.662
