Di¤erential geometry has found fruitful application in statistical inference. In particular, Amari's (1990) expected geometry is used in higher order asymptotic analysis, and in the study of su¢ciency and ancillarity. However, we can see three drawbacks to the use of a di¤erential geometric approach in econometrics and statistics more generally. Firstly,(More)
This paper lays the foundations for a unified framework for numerically and computationally applying methods drawn from a range of currently distinct geometrical approaches to statistical modelling. In so doing, it extends information geometry from a manifold based approach to one where the simplex is the fundamental geometrical object, thereby allowing(More)
This whitepaper is designed to provide a basic understanding of the main concepts of the DO-254 compliance specification for electronic component design. It outlines the major steps involved in a DO-254 compliant ASIC/FPGA design and verification process, and explains how differentiating tool features can be mapped to enhance and facilitate critical stages(More)
