MODEL-PRESERVING PARAMETRIC
CONSTRAINTS AND THEIR ROLE

25 Maggio 2001
ore 16.00
Aula SC60


Summary

The notion of identifiable and model-preserving parametric constraints are 
introduced from a general viewpoint. It is proposed that a hypothesis, 
apparently non-testable, may be tested by considering its equivalent 
identifiable parametric constraints. For a linear model, a necessary and 
sufficient condition for a set of constraints to be model-preserving is 
obtained. The results have significant impact for non-identifiable parametric 
models, especially for linear models.

Gli interessati sono cordialmente invitati ad intervenire.

Per informazioni si prega di contattare il sig. Dicuonzo 
(marius@mailhost.stat.unipd.it) della segreteria del 
Dipartimento.
