Choosing the best among peers

Choosing the Best Bundle of Projects: A DEA Approach

Choosing peers: Homophily and polarization in groups

This paper studies the formation of peer groups entailing the joint production of public goods. In our model agents choose their peers and have to pay a connection cost for each member added to the group. After groups are formed, each agent selects a public project to make a costly contribution to, and all members of the group experience the benefits of these contributions. Since agents differ ...

Adaptively Choosing the Best Procedure for Selecting the Best System

This paper presents a method that uses initial sample data to choose between statistical procedures for identifying the simulated system with the best (maximum or minimum) expected performance. The method chooses the procedure that minimizes the additional number of simulation replications required to return a pre-specified probability guarantee. This problem may be encountered after a heuristi...

Choosing the Best Comparison Under the Circumstances

The Methodius Natural Language Generation systems generates personalized descriptions of objects from a collection. As part of the user modeling component, it creates comparisons between the current object being viewed and previous objects from the user history. We present our general algorithm for choosing the best comparison, which can be optimized to give the best result for different domain...

Preventing ischemic stroke: choosing the best strategy.

Many questions remain about specific strategies to prevent first or subsequent stroke: Do statins prevent stroke? Which antithrombotic drugs are best? What is the best way to treat carotid stenosis? We review current evidence on drug therapy and surgical options, addressing key stroke risk factors: ie, hypertension, atherosclerosis, atrial fibrillation, patent foramen ovale, aortic stenosis, an...
