The Statistics of Statistical Arbitrage [PDF]
Financial Analysts Journal, 2007 Hedge 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.

This chapter gives definitions and basics on statistics, as mean standard deviation, trueness, accuracy, uncertainty … The relation of test result precision with the number of test readings is emphasized. Theoretical considerations about the minimal distance between two test readings to ensure their dependency are presented.

Statistics, Adjusted Statistics, and Maladjusted Statistics
American Journal of Law & Medicine, 2017Statistical adjustment is a ubiquitous practice in all quantitative fields that is meant to correct for improprieties or limitations in observed data, to remove the influence of nuisance variables or to turn observed correlations into causal inferences. These adjustments proceed by reporting not what was observed in the real world, but instead modeling

Order Statistics and Nonparametric Statistics. [PDF]
, 1978 Abstract : 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

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.
