You are in a specific LISREL-taught course or want to learn SIMPLIS syntax. Avoid it if: You have a dataset with more than 15 variables, more than 150 cases, or need to generate high-quality publication figures directly from the software.

LISREL is unique because it uses two different coding languages:

Furthermore, it limits the number of . In complex models, you cannot estimate more than a certain number of coefficients (usually around 100-150). If your model has 200 regression paths, the student version will crash or throw an "ESTIMATION FAILED" error due to memory limits.

It forces the user to understand the matrix algebra and structural equations behind the pretty diagrams.
