Places equality constraints on model parameters.
Syntax
object.Model (modelName, constraint1)
object.Model (modelName, constraint1, constraint2)
object.Model (modelName, constraint1, constraint2, constraint3)
...
The Model method syntax has the following parts:
Part |
Description |
object |
An object of type AmosEngine. |
modelName |
A name for the complete set of constraints consisting of constraint1, constraint2, constraint3, etc. |
constraint1 |
Either: A string of the form p1=p2=p3=..., where each pi is either a parameter name or a number. At most one of the pi can be a number. Or: The name of a model defined by another use of the Model method. |
constraint2 |
Same as constraint1 |
constraint3 |
Same as constraint1 |
... |
... |
Placement: [2].
Default
No additional parameter constraints are imposed beyond those specified by the assignment of names and values to parameters by use of the Path, Cov, Var, Mean, Intercept, AStructure and MStructure methods.
Remarks
In order to use the Model method, you need to be able to refer to parameters by name. Parameters can be named by the Path, Cov, Var, Mean, Intercept, AStructure and MStructure methods.
You can use the Model method as many times as you want.
