sPlot: A QUICK INTRODUCTION
نویسنده
چکیده
The paper advocates the use of a statistical tool dedicated to the exploration of data samples populated by several sources of events. This new technique, called sP lot, is able to unfold the contributions of the different sources to the distribution of a data sample in a given variable. The sP lot tool applies in the context of a Likelihood fit which is performed on the data sample to determine the yields of the various sources.

sFit: a method for background subtraction in maximum likelihood fit
This paper presents a statistical method to subtract background in maximum likelihood fit, without relying on any separate sideband or simulation for background modeling. The method, called sFit, is an extension to the sPlot technique originally developed to reconstruct true distribution for each date component. The sWeights defined for the sPlot technique allow to construct a modified likeliho...
متن کاملAlert Management Systems: A Quick Introduction
We describe a type of data mining system designed to screen events, build profiles associated with the events, and send alerts based upon the profiles and events. These types of systems are becoming known as alert management systems (AMS). We give some examples of alert management systems and give a quick introduction to their architecture and functionality.
