LCA model parameterization characteristics.
| Model Number | Means | Variances | Covariances | Interpretation | |
|---|---|---|---|---|---|
| Class-Invariant Parameterization (CIP) |
Varying | Equal | Zero | Different classes/profiles have different means on BSMAS symptoms. Despite this, the differences of the minimum and maximum rates for the six BSMAS symptoms do not significantly differ across the classes/profiles. Finally, there is no covariance in relation to the six BSMAS symptoms across the profiles. | |
| Class-Varying Diagonal Parameterization (CVDP) |
Varying | Varying | Zero | Different classes/profiles have different means on BSMAS symptoms but similar differences between their minimum and maximum scores. Additionally, there is an existing similar pattern of covariance considering the six BSMAS symptoms across the classes. | |
| Class-Invariant Unrestricted Parameterization (CIUP) |
Varying | Equal | Equal | Different classes in the model have different means on the six BSMAS symptoms. The range between the minimum and maximum scores of the six BSMAS symptoms is dissimilar across the profiles. Last, there is differing covariance based on the six BSMAS symptoms across the classes. | |
| Class-Varying Unrestricted Parameterization (CVUP) |
Varying | Varying | Varying | Different classes in the model have different means on the six BSMAS symptom. The range between the minimum and maximum scores of the six BSMAS symptoms is dissimilar across the profiles. Last, there is differing covariance based on the six BSMAS symptoms across the classes. |
