Published / Preprint: Highly comparative time-series analysis: The empirical structure of time series and their methods

Posted: 05 Apr 2013 01:19 AM PDT

The process of collecting and organizing sets of observations represents a common theme throughout the history of science. However, despite the ubiquity of scientists measuring, recording, and analyzing the dynamics of different processes, an extensive organization of scientific time-series data and analysis methods has never been performed. Addressing this, annotated collections of over 35 000...

Published / Preprint: Analysis of bibliometric indicators for individual scholars in a large data set

Posted: 05 Apr 2013 01:05 AM PDT

Citation numbers and other quantities derived from bibliographic databases are becoming standard tools for the assessment of productivity and impact of research activities. Though widely used, still their statistical properties have not been well established so far. This is especially true in the case of bibliometric indicators aimed at the evaluation of individual scholars, because large-scale...

Published / Preprint: Happiness and the Patterns of Life: A Study of Geolocated Tweets

Posted: 05 Apr 2013 01:05 AM PDT

The patterns of life exhibited by large populations have been described and modeled both as a basic science exercise and for a range of applied goals such as reducing automotive congestion, improving disaster response, and even predicting the location of individuals. However, these studies previously had limited access to conversation content, rendering changes in expression as a function of...

Published / Preprint: Five Misunderstandings About Case-Study Research. (arXiv:1304.1186v1 [q-fin.GN])

Posted: 04 Apr 2013 05:36 PM PDT

This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most useful for generating hypotheses, while other methods are more suitable for hypotheses testing and...

Published / Preprint: Interest-Rate Modelling in Collateralized Markets: Multiple curves, credit-liquidity effects, CCPs. (arXiv:1304.1397v1 [q-fin.PR])

Posted: 04 Apr 2013 05:36 PM PDT

The market practice of extrapolating different term structures from different instruments lacks a rigorous justification in terms of cash flows structure and market observables. In this paper, we integrate our previous consistent theory for pricing under credit, collateral and funding risks into term structure modelling, integrating the origination of different term structures with such effects....

Published / Preprint: Fluctuation Analysis for the Loss From Default. (arXiv:1304.1420v1 [math.PR])

Posted: 04 Apr 2013 05:36 PM PDT

We analyze the fluctuation of the loss from default around its large portfolio limit in a class of reduced-form models of correlated firm-by-firm default timing. We prove a weak convergence result for the fluctuation process and use it for developing a conditionally Gaussian approximation to the loss distribution. Numerical results illustrate the accuracy and computational efficiency of the...

Blog Post: Falkenblog: My Favorite Quotes

Posted: 04 Apr 2013 05:17 PM PDT

OK, one day into blogging retirement and I'm posting, but some asked in the comments for the quote list I mentioned, which I thought I'd share. I know I'm missing hundreds more good ones, and some here are much better than others. That is, 'moderation in all things' is highly profound. In contrast, I don't agree that "Genius is only a greater aptitude for patience", but I do think patience is...
