- Correlation matrix with standard deviations of the observed variables, rounding to three decimal place (Hoyle&Panter,1995) -- the most generous report
- covariance matrix + means of the observed variables. Even if your SEM doesn't concern means, the means of all observed variables should be reported in written sumary for other researchers to re-run the SEM
- to get covariance matrix in Amos, view -- text output--sample moment (sample covariance matrix
- correlation matrix + standard deviation of all observed variables + (means)
- It is highly recommended to provide means for covariance matrix or correlation matrix+ standard deviation
- When data are not interval-level data, the data need be preprocessed so that a tetrachoric matrix (for dichotomous data) or polychoric matrix (for ordered-categorical variables) is estimated and analyzed in SEM.
- When additional assumptions are made about the measurement level of the raw data in the model, such assumptions should be explicitly reported.
- Information about univariate and multivariate distribution should be presented and interpreted.
