Pricing with Samples

Operations Research, 2022
This paper studies the value of data for pricing purposes. Although pricing is central across industries, little is known about the minimal amount of data needed to achieve good pricing decisions. The present paper proposes a novel approach to quantify the informational content of data, through the introduction of a new class of robust data-driven ...

TO SAMPLE OR NOT TO SAMPLE

The Manchester School, 2006
Suppose a prospective oil field is partitioned into a finite number of lots. Conventional wisdom suggests that failing to find oil on one lot is bad news regarding subsequent exploration of other lots, due to a ‘common pool’ effect. Here we identify situations where failing to find oil on a lot may be good news.

Sampling and sampled-data models

Proceedings of the 2010 American Control Conference, 2010
Physical systems typically evolve continuously whereas modern controllers and signal processing devices invariably operate in discrete time. Hence sampling arises as a cornerstone problem in essentially all aspects of modern systems science. This paper reviews various aspects of sampling of signals and systems.

Sampling bessel functions and bessel sampling

2013 IEEE 8th International Symposium on Applied Computational Intelligence and Informatics (SACI), 2013
The main aim of this article is to establish summation formulae in form of sampling expansion series for Bessel functions , and , and obtain sharp truncation error upper bounds occurring in the –Bessel sampling series approximation. The principal derivation tools are the famous sampling theorem by Kramer and various properties of Bessel and modified ...
