Hi,

I have 50 binary variables with values of either 0 or 1. I tried to treat these variables as ordinal and fit a growth curve model.

OpenMx gave wrong message:

Running Linear Growth Curve Model

Error: The data object 'Linear Growth Curve Model.data' contains 50 ordered factors but our ordinal integration implementation has a limit of 20 ordered factors.

Is that true that I only can fit 20 ordered factors using OpenMx? Could you point me a direction how to fix this problem? Any help or suggestions will be appreciated. Thanks!
