Notes for Model (Default model)

Computation of degrees of freedom (Default model)

Number of distinct sample moments:	119
Number of distinct parameters to be estimated:	50
Degrees of freedom (119 - 50):	69

Result (Default model)
The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 3 additional constraints.
