The Statistics of Statistical Arbitrage
Financial Analysts Journal, 2007Hedge funds sometimes use mathematical techniques to “capture” the short-term volatility of stocks and perhaps other types of securities. This sort of strategy resembles market making and is sometimes considered a form of statistical arbitrage. This study shows that for the universe of large-capitalization U.S.

Statistical Mechanics for a Class of Quantum Statistics
Physical Review Letters, 1994Generalized statistical distributions for identical particles are introduced for the case where filling a single-particle quantum state by particles depends on filling states of different momenta. The system of one-dimensional bosons with a two-body potential that can be solved by means of the thermodynamic Bethe ansatz is shown to be equivalent ...

Molecular Ecology, 2002
While studies of phylogeography and speciation in the past have largely focused on the documentation or detection of significant patterns of population genetic structure, the emerging field of statistical phylogeography aims to infer the history and processes underlying that structure, and to provide objective, rather than ad hoc explanations.

Statistical models and statistical inference
1981In the previous chapter we have seen how a simple statistical model can be fitted to data by estimating the unknown parameters and then making checks with residuals. After we have done this, various questions can be answered in terms of the fitted model.

Order Statistics and Nonparametric Statistics.
1978Abstract : The research reported falls under the headings: (a) order statistics; (b) competing risks; (c) nonparametric statistics, and (d) cyclic designs. (a) Concomitants of order statistics were introduced and studied as a class, and applications in selection and double sampling provided. The robustness of various estimators of location and scale in

Statistics and Statistical Hypotheses
2019Abstract This chapter covers statistics from a conceptual rather than a quantitative perspective. The objective is to distinguish statistical from scientific hypotheses and provide background for later discussions. The fact that scientific and statistical hypotheses are dissimilar is often overlooked, and the chapter shows how they ...

Basic Statistics, Statistical Design, and Critical Analysis of Statistics for Surgeons
Clinics in Podiatric Medicine and SurgeryStatistics is a set of tools used in medical decision-making no different than how a scalpel or a sagittal saw is used in the operating room. No foot and ankle surgeon is born with the inherent ability to perform, understand, and critically interpret them.
