Honesty and Integrity in Economics

Mayer, Thomas - Economics Department, University of California-Davis - 2009

Principal component analysis-based frequent pattern evaluation on the object-relational data model of a cricket match database

UmaMaheswari, P.; Rajaram, M. - In: International Journal of Data Analysis Techniques and … 1 (2009) 4, pp. 364-384

Frequent pattern evaluation is imperative for cricket match data to develop more proficient coaching strategies and progress the performance of individual players. The rapid growth in size of the match database far exceeds the human ability to analyse, thus creating an opportunity to extract...

COMPUTING AMBIGUITY IN COMPLEX SYSTEMS WITH FUZZY LOGIC

Iandoli, L.; Marchione, E.; Ponsiglione, C.; Zollo, . - In: Fuzzy Economic Review XIV (2009) 1, pp. 3-30

This paper introduces a new and novel deterministic technique for mining association rules from quantitative data tables and databases and show how to use these techniques to devise a fuzzy-inference based apriori algorithm for discovering associations. The algorithm is sound and efficient. It...

Computer Automation of General-to-Specific Model Selection Procedures

Hendry, David; Krolzig, Hans-Martin - Department of Economics, Oxford University - 2000

Disputes about econometric methodology partly reflect a lack of evidence on alternative approaches. We reconsider econometric model selection from a computer-automation perspective, focusing on general-to-specific reductions, embodied in PcGets. Starting from a general congruent model, standard...

General-to-Specific Reductions of Vector Autoregressive Processes

Krolzig, Hans-Martin - Department of Economics, Oxford University - 2000

Unrestricted reduced form vector autoregressive (VAR) models have become a dominant research strategy in empirical macroeconomics since Sims (1980) critique of traditional macroeconometric modeling. They are however subjected to the curse of dimensionality. In this paper we propose...
