On the testability of the CAR assumption

چکیده
In recent years a popular non-parametric model for coarsened data is an assumption on the coarsening mechanism called Coarsening At Random (CAR). We will give a short definition here; in the talk we will introduce a more general version. Let Y be the space of the parameter of interest Y . On Y we have a dominating measure Q0. Let C be a space with a dominating measure P0 such that the data contains the coarsening variable C ∈ C and a function of Y and C, so X = (C, φ(C, Y ).

On the Testability of the Car Assumption
In recent years a popular nonparametric model for coarsened data is an assumption on the coarsening mechanism called coarsening at random (CAR). It has been conjectured in several papers that this assumption cannot be tested by the data, that is, the assumption does not restrict the possible distributions of the data. In this paper we will show that this conjecture is not always true; an exampl...
متن کاملEvaluating Conceptual Modeling Languages
An important assumption for many KA researchers is structure preservation ; i.e. conceptual models can be converted in a straight forward manner into a design for an implementation. This assumption may not always hold. Seemingly trivial variants in a qualitative conceptual models can block pragmatically desirable properties such as KB-testability and KB-maintainability. KB-testability and KB-ma...
متن کاملDesign and implementation of an automatic car turning system
In this paper, a control system is designed for automatic car turning. At first, the necessary information of car turning that were collected from the traffic bylaw, car driving training centers and traffic police are explained. Then, car turning is studied experimentally on several streets with different widths. Afterward, a proper path is designed for the automatic car turning system consider...
متن کاملCoupled Axial-Radial Vibration of Single-Walled Carbon Nanotubes Via Doublet Mechanics
This paper investigates the coupled axial-radial (CAR) vibration of single-walled carbon nanotubes (SWCNTs) based on doublet mechanics (DM) with a scale parameter. Two coupled forth order partial differential equations that govern the CAR vibration of SWCNTs are derived. It is the first time that DM is used to model the CAR vibration of SWCNTs. To obtain the natural frequency and dynamic respon...
متن کاملHow to Test for Multiple Realization
When conceived as an empirical claim, it is natural to wonder how one might test the hypothesis of multiple realization. I consider general issues of testability, show how they apply specifically to the hypothesis of multiple realization, and propose an auxiliary assumption that, I argue, must be conjoined to the hypothesis of multiple realization to ensure its testability. I argue further that...
