Informativity and robustness

O'Neill, Ben


This paper investigates robustness problems involving non response or other nuisance parameters. The minimal sufficient parameter is introduced and shown to completely capture the information provided by data. The concept of informativity is then introduced that serves to determine, in some sense, whether statistical models provide any information about inferential quantities of interest. These concepts are shown to lead to useful robustness results involving inferences under perfect...[Show more]
