The infinite Viterbi alignment and decay-convexity

The infinite Viterbi alignment is the limiting maximum a-posteriori estimate of the unobserved path in a hidden Markov model as the length of the time horizon grows. For models on state-space Rd satisfying a new “decay-convexity” condition, we develop an approach to existence of the infinite Viterbi alignment in an infinite dimensional Hilbert space. Quantitative bounds on the distance to the Viterbi process, which are the first of their kind, are derived and used to illustrate how approximate estimation via parallelization can be accurate and scaleable to high-dimensional problems because the rate of convergence to the infinite Viterbi alignment does not necessarily depend on d. The results are applied to approximate estimation via parallelization and a model of neural population activity

British Election Study, 2005: Comparative Study of Electoral Systems

<p>Abstract copyright UK Data Service and data collection copyright owner.</p>The <i>British Election Study, 2005: Comparative Study of Electoral Systems</i> (CSES) dataset forms part of the CSES programme of collaborative research among election study teams from around the world. The research agenda, questionnaires, and study design are developed by an international committee of leading scholars of electoral politics and political science. The design is implemented in each country by leading social scientists. Participating countries include a common module of survey questions in their post-election studies. The resulting data are combined with voting, demographic, district and macro variables, and each country's data is then merged into a single, free, public dataset for use in comparative research.<br> <br> The BES 2005 CSES data were gathered via an internet survey carried out by YouGov plc. The survey was conducted after the 5 May 2005 general election, between 16 and 31 May. Nearly 90% of the interviews were completed between 16 and 18 May.<br> <br> Further information about the international programme may be found on the <a href="http://www.umich.edu/~cses/" title="Comparative Study of Electoral Systems">CSES</a> web site.<br> <br
