We apply and evaluate a decision tree algorithm to university records, producing human-readable graphs that are useful both for predicting graduation, and understanding factors that lead to graduation. We compare this method to that of nueral networks, Support Vector Machines, and Kernel Regression, and show that it is equally powerful as a classificaion tool. At the same time, decision trees p...

Factors distinguishing clients who complete drug court treatment from those who do not complete drug court have been documented, but differences between urban and rural drug court participants have not been examined. The present study focuses on examining mental health, drug use, criminal activity, and education/employment as factors that are associated with treatment retention, which is measur...

Graduation of data is of great importance in survival analysis. Smoothness and goodness of fit are two fundamental requirements in graduation. Based on the instinctive defining expression for entropy in terms of a probability distribution, two optimization models based on the Maximum Entropy Principle (MaxEnt) and Minimum Cross Entropy Principle (MinCEnt) to estimate mortality probability distr...

In this paper we estimate the effect of the change from a loan-based to a grant-based student financial aid system on the graduation times. Starting from simple assumptions on how the explanatory variables affect study intensity, we derive the duration distribution for the times-to-degree that turns out to follow a two parameter Gamma distribution. We then show that the effect of the time-varyi...

9 One of the theoretically important factors for incubator firm performance is the strength of their linkages to the research university sponsoring the technology incubator. Herein, we focus on two types of university linkages to the sponsoring institution: a license obtained from the university and a link to university faculty, while controlling for incubator firm linkages to nonsponsoring res...
