The forensic determination of carboxyhemoglobin (COHb) in blood was performed by using an improved principal component regression (PCR) technique applied to UV-visible spectra. Calibration data were decomposed into principal components, and the princ

The unreliability of multivariate outlier detection techniques such as Mahalanobis distance and hat matrix leverage has been known in the statistical community for well over a decade. However, only within the past few years has a serious effort been

This paper assesses the autocorrelation patterns in U.S. stock market indices: the S&P 500 (1962-2007), the Dow Jones Industrial Average (1929-2007), and the NASDAQ Composite (1972-2007). Statistically significant lag 1 autocorrelation was observed f

This paper examines the fit of three different statistical distributions to the returns of the S&P 500 Index from 1950-2005. The normal distribution is a poor fit to the daily percentage returns of the S&P 500. The lognormal distribution is a poor fi
