i have run a non linear growth curve and i want to test if each of the estimated beta coefficient is significantly different from expected the linear coefficient:
so test if .612 is significantly different from .67 (see the following output).

This is the Mplus output.

PBS_3 0.612 0.123 4.962 0.000
PBS_4 1.000 0.000 999.000 999.000

Any suggestion is appreciated

The test of the difference between the linear and estimated coefficient is, for example,

(.612 - .666)/.123
