PCMParamType: Parameter types

Description

The parameter types are divided in the following categories:

Main type

These are the "ScalarParameter", "VectorParameter" and "MatrixParameter" classes. Each model parameter must have a main type.

Scope/Omission

These are the "_Global" and "_Omitted" classes. Every parameter can be global for all regimes or local for a single regime. If not specified, local scope is assumed. In some special cases a parameter (e.g. Sigmae can be omitted from a model. This is done by adding "_Omitted" to its class attribute.

Constancy (optional)

These are the "_Fixed", "_Ones", "_Identity" and "_Zeros" classes.

Transformation (optional)

These are the "_Transformable", "_CholeskyFactor" and "_Schur" classes.

Other properties (optional)

These are the "_NonNegative", "_WithNonNegativeDiagonal", "_LowerTriangular", "_AllEqual", "_ScalarDiagonal", "_Symmetric", "_UpperTriangular", "_LowerTriangularWithDiagonal" and "_UpperTriangularWithDiagonal" classes.
