Specifies a regression weight as a model parameter.
Syntax
object.Path (leftVariableName, rightVariableName)
object.Path (leftVariableName, rightVariableName, parameterValue)
object.Path (leftVariableName, rightVariableName, parameterName)
The Path method syntax has the following parts:
Part |
Description |
object |
An object of type AmosEngine. |
leftVariableName rightVariableName |
The character strings, leftVariableName and rightVariableName, are the names of two variables. leftVariableName depends linearly on rightVariableName. That is, leftVariableName is on the left-hand side of a regression equation and rightVariableName appears on the right-hand side with a regression weight that is a model parameter. |
parameterValue |
(Optional) Parameter value. If parameterValue = 3, say, then the regression weight is fixed at 3. |
parameterName |
(Optional) Parameter name. If parameterName = "abc", say, then the regression weight is named "abc". It is constrained to be equal to any other parameters named "abc". If parameterName = "3?", say then the regression weight is given an initial value of 3, and is unconstrained. If parameterName = "abc:3", say, then the regression weight is named "abc" and is given an initial value of 3. It is constrained to be equal to any other parameters named "abc". If parameterName is an empty string (""), the regression weight is an unconstrained parameter. |
Placement: [2].
Default
A variable is assumed not to depend directly on another variable unless a linearly dependency is specified by use of the Path or AStructure method.
Remarks
If parameterValue and parameterName are omitted, the regression weight is an unconstrained parameter.
