This site has been migrated from mywebspace.wisc.edu which UW Madison is shutting down. 

The material from the old site has been converted to pdf documents available under Links in the right-hand navigation column. 

Documents and links that were stale have been deleted. If you are looking for something or having trouble with any of the permissions, please email me at the link below.

Most of my new activities will be shifted to blogs and other public sites listed on the right:

• Random Variation covers statistical analysis and modeling.

• Random Stock Walker presents statistical models of stocks and of the US Stock Market.

• Facts, Fictions and Forecasts reports macro-level forecasts for the world system and individual countries.

• Golf Facts, Fictions and Systems investigates what is known about the golf swing.

• My Blog is a catch-all for postings of general interest.

• The pasdirtz YouTube channel posts video I have taken.

• Jazz, Blues and the Abstract Truth is devoted to Jazz guitar (particularly Wes Montgomery) and associated music theory.

• Causal Macro Systems presents the theory behind current macro-societal and macro-economic models, to include integrated assessment models.

• Economic Bubble Machine explores statistical approaches to identifying economic bubbles before they pop.

• World System Conjectures reviews the World Systems Approach and derives testable propositions from the qualitative analysis.

The remaining links should be somewhat self-explanatory.
