Steele et al. (2005) describe a general framework for the analysis of correlated event histories, with an application to a study of partnership transitions and fertility among a cohort of British women. A multilevel multistate competing risks model is used to examine the relationship between prior fertility outcomes (the presence and characteristics of children and current pregnancy) and the di...

Results on the simultaneous scaling of nonnegative matrices involving one sided inequalities are presented. These are applied to scalings involving two sided inequalities. The proofs are graph theoretic. The setting is generalized to matrices with elements in lattice ordered Abelian groups with 0.

This note revisits the identification theorems of B. Brown (1983) and Roehrig (1988). We describe an error in the proofs of the main identification theorems in these papers, and provide an important counterexample to the theorems on the identification of the reduced form. Specifically, contrary to the theorems, the reduced form of a nonseparable simultaneous equations model is not identified ev...

Ground-level ozone concentration is a key indicator of air quality. There may exist sudden changes in ozone concentration data over a long time horizon, which may be caused by the implementation of government regulations and policies, such as establishing exhaust emission limits for on-road vehicles. To monitor and assess the efficacy of these policies, we propose a methodology for detecting ch...

We consider the problem of simultaneous nite gain L p-stabilization and internal stabilization of linear systems subject to input saturation via linear static state feedback. We show that bounded input nite-gain L p-stabilization and local asymptotic stabilization can always be achieved simultaneously no matter where the poles of the open loop system are, and the locations of these poles play a...

Some e-shops present product attributes in structured form, but many others use the textual description only. Attributes of products are essential in automated product deduplication. We suggest methods for automated extraction of attributes and their values from product descriptions to a structural form. The structural data extracted from other e-shops are used as background knowledge.

This note is a resume of Jerry Hausman’s Nake course at the NAKE workshop in Den Haag, The Netherlands in June 2002. It presents an intuitive framework in which the impact of weak/invalid instruments on properties of di¤erent estimators can be analyzed while also suggesting a test to detect the presence of weak/invalid instruments.

Conventional work on scienti c discovery such as BACON derives empirical law equations from experimental data. In recent years, SDS introducing mathematical admissibility constraints has been proposed to discover rst principle based law equations, and it has been further extended to discover law equations from passively observed data. Furthermore, SSF has been proposed to discover the structure...
