![Simulate regression models that incorporate CLASS parameterizations](https://blogs.sas.com/content/iml/files/2017/01/ProgrammingTips-2.png)
When you write a program that simulates data from a statistical model, you should always check that the simulation code is correct. One way to do this is to generate a large simulated sample, estimate the parameters in the simulated data, and make sure that the estimates are close to
