The APL character reaches out from the distant past to continue to plague me - another reason to re-write this in J.
When I look at both documents on my machine, I see all the APL except for the domino-quads in the MultiVDLM3 function: in the PDF, this is rendered as a bold, san-serif, capital "z" with a "caron" (http://en.wikipedia.org/wiki/Caron) accent. This infernal character set also continues to teach me new things! I've put a picture of the final APL function from the paper here: http://www.jsoftware.com/jwiki/DevonMcCormick/DynamicLinearModels/BayesianFinancialDynamicLinearModel .
