Exact Sampling And Prefix Distributions, Sebastian Oberhoff

Theses and Dissertations

This thesis explores some new means to generate random numbers without incurring any numerical

inaccuracies along the way. In the context of continuous distributions this leads to the discussion of

prex distributions { discrete distributions that fully capture a continuous distribution by describing

their initial digits. These are rst studied graphically, then analytically, which also leads to a general

examination of the behavior of the distribution of trailing digits of continuous distributions. Finally,

some slightly novel, related results from the theory of computation are presented.

Text Classification Of Installation Support Contract Topic Models For Category Management, William C. Sevier

Theses and Dissertations

Air Force Installation Contracting Agency manages nearly 18 percent of total Air Force spend, equating to approximately 57 billion dollars. To improve strategic sourcing, the organization is beginning to categorize installation-support spend and assign accountable portfolio managers to respective spend categories. A critical task in this new strategic environment includes the appropriate categorization of Air Force contracts into newly created, manageable spend categories. It has been recognized that current composite categories have the opportunity to be further distinguished into sub-categories leveraging text analytics on the contract descriptions. Furthermore, upon establishing newly constructed categories, future contracts must be classified into these …
