I am trying to better understand how Mplus works. We are estimating a LCMG model and we wanted compare results from Mplus and results from SAS. We have been estimating 4 classes in SAS three of them included the quadratic growth factor while in Mplus we got non significant values neither in the quadratic factor nor in the slope. Is this has sense? Which could be the explanation?

Thanks in advance

First check if your SAS and Mplus runs have the same number of parameters so that they are comparable. If so, send outputs to Support along wit your license number.
