Topics in statistical finance

2008
This thesis is divided into three parts. The first part investigates the presence of long term dependence in stock price data via a permutation test based on the correlation structure of the underlying stock prices. These tests reveal the short term nature of stock price dependence structure.

Topics in Statistical Pattern Recognition

1976
Pattern recognition, from the broadest viewpoint, is the study of how one puts abstract objects or patterns into categories in a simple reliable way. We have chosen three areas to review: Nonparametric Discrimination, Finite Memory Learning, and Pattern Complexity.

Topics in Statistical Oceanography

1996
The aim of this paper is to review some recent results in Lagrangian analysis. These results concentrate on the very old and classical problem of the transition from Lagrangian statistics, drifter trajectories, to Eulerian data. In this area the number of physics publications is incredibly large, and it is difficult to find formulas which are not ...

A Statistical Model for Topically Segmented Documents [PDF]

, 2011
Generative models for text data are based on the idea that a document can be modeled as a mixture of topics, each of which is represented as a probability distribution over the terms. Such models have traditionally assumed that a document is an indivisible unit for the generative process, which may not be appropriate to handle documents with an ...

Statistical Topics in the Laboratory Sciences

2007
This chapter concerns statistical concepts and procedures that are applicable to diagnostic testing performed in the clinical laboratory. Three important laboratory issues are addressed: the estimation of analytical imprecision, the design of an effective laboratory quality control strategy, and the establishment of population reference ranges.

Special Topics: Statistical Power

2013
As we have seen in earlier chapters, criminal justice researchers place a premium on statistical inference and its use in making decisions about population parameters from sample statistics. In assessing statistical significance, The focus is the problem of Type I, or alpha (α), error the risk of falsely rejecting the null hypothesis.

Statistical Models of Topical Content

2002
In this chapter we explore the behavior of two different statistical models, one based on simple unigrams and another based on the beta-binomial distribution, as applied to the problem of modeling story generation. We describe how these models can be incorporated into information extraction applications, particularly Tracking and Detection engines ...
