Event Selection Using an Extended Fisher Discriminant Method
This note discusses the problem of choosing between hypotheses in a situation with many, correlated non-normal variables. A new method is introduced to shrink the many variables into a smaller subset…

Multivariate Analysis from a Statistical Point of View
Multivariate Analysis is an increasingly common tool in experimental high energy physics; however, many of the common approaches were borrowed from other fields. We clarify what the goal of a…

Frequentist Hypothesis Testing with Background Uncertainty
We consider the standard Neyman-Pearson hypothesis test of a signal-plus-background hypothesis and background-only hypothesis in the presence of uncertainty on the background-only prediction.…

Model reconstruction of nonlinear dynamical systems driven by noise
An efficient technique is introduced for model inference of complex nonlinear dynamical systems driven by noise. The technique does not require extensive global optimization, provides optimal…

Image reconstruction without prior information
A novel framework for designing image reconstruction algorithms for linear forward problems is proposed. The framework is based on the novel concept of conserving the information in the data during…

Multilevel Clustering Fault Model for IC Manufacture
A hierarchical approach to the construction of compound distributions for process-induced faults in IC manufacture is proposed. Within this framework, the negative binomial distribution is treated as…

An Object-Oriented Approach to Partial Wave Analysis
Partial Wave Analysis has traditionally been carried out using a set of tools handcrafted for each experiment. By taking an object-oriented approach, the design presented in this paper attempts to…

Spatial methods for event reconstruction in CLEAN
In CLEAN (Cryogenic Low Energy Astrophysics with Noble gases), a proposed neutrino and dark matter detector, background discrimination is possible if one can determine the location of an ionizing…

The probability of making a correct decision in hypotheses testing as estimator of quality of planned experiments
In the report the approach to estimation of quality of planned experiments is considered. This approach is based on the analysis of uncertainty, which will take place under the future hypotheses…

Optimal embedding parameters: A modelling paradigm
Reconstruction of a dynamical system from a time series requires the selection of two parameters, the embedding dimension de and the embedding lag τ. Many competing criteria to select these…

On Statistical Methods of Parameter Estimation for Deterministically Chaotic Time-Series
We discuss the possibility of applying some standard statistical methods (the least square method, the maximum likelihood method, the method of statistical moments for estimation of parameters) to…

A generic scheme for choosing models and characterizations of complex systems
It is argued that the two problems of choosing characterizations and models of complex systems should not be considered independently. A particular criterion for these choices, oriented on the…

Maximum Entropy method with non-linear moment constraints: challenges
Traditionally, the Method of (Shannon-Kullback's) Relative Entropy Maximization (REM) is considered with linear moment constraints. In this work, the method is studied under frequency moment…
