  1. *Indicator variances on the diagonal, indicator covariances below the diagonal, and correlations of the corresponding latent exogenous variables obtained from LISREL's standardized phi matrix in bold above the diagonal. Correlations between any pair of latent indicators can be calculated from the lower triangular entries by dividing the covariance between the indicators by the square root of the product of the two relevant variances Cov ( XY ) / Var(X) Var(Y) MathType@MTEF@5@5@+=feaafiart1ev1aaatCvAUfKttLearuWrP9MDH5MBPbIqV92AaeXatLxBI9gBaebbnrfifHhDYfgasaacPC6xNi=xH8viVGI8Gi=hEeeu0xXdbba9frFj0xb9qqpG0dXdb9aspeI8k8fiI+fsY=rqGqVepae9pg0db9vqaiVgFr0xfr=xfr=xc9adbaqaaeGaciGaaiaabeqaaeqabiWaaaGcbaGaee4qamKaee4Ba8MaeeODayNaeiikaGIaeeiwaGLaeeywaKLaeiykaKIaei4la8YaaOaaaeaacqqGwbGvcqqGHbqycqqGYbGCcqqGOaakcqqGybawcqqGPaqkcqqGGaaicqqGwbGvcqqGHbqycqqGYbGCcqqGOaakcqqGzbqwcqqGPaqkaSqabaaaaa@4342@
