Speech Detection Using High Order Statistic (Skewness)

In this article we discuses one of many possible applications of high order statistic (HOS) to speech detection problem. As a speech feature we used skewness or thirdorder cumulant with two zero lags in a simple voiced speech detection algorithm. We compared its properties with the energy feature in symmetric noises, speech signals and in various signal to noise ratios (SNR). These results proo...

The Skewness of the Aperture Mass Statistic

We present simple formulae for calculating the skewness and kurtosis of the aperture mass statistic for weak lensing surveys which is insensitive to masking effects of survey geometry or variable survey depth. The calculations are the higher order analogs of the formula given by Schneider, van Waerbeke & Mellier (2002) which has been used to compute the variance of the aperture mass from severa...

A Simple Transformation Method in Skewness Reduction

Statistical analysis of non-normal data is usually more complicated than that for normaldistribution. In this paper, a simple root/power transformation technique developed by Niaki, et al [1]is extended to transform right and left skewed distributions to nearly normal. The value of theroot/power is explored such that the skewness of the transformed data becomes almost zero with anacceptable err...

Forgotten marriages? Measuring the reliability of marriage histories

BACKGROUND Marriage histories are a valuable data source for investigating nuptiality. While researchers typically acknowledge the problems associated with their use, it is unknown to what extent these problems occur and how marriage analyses are affected. OBJECTIVE This paper seeks to investigate the quality of marriage histories by measuring levels of misreporting, examining the characteris...

Measuring Privacy Concern and the Right to Be Forgotten

The ‘right to be forgotten’ (RTBF) is an emerging concept that refers to an individual’s ability to have data collected about themselves permanently deleted or “destroyed”—the final stage of the information life cycle. However, we do not yet understand where RTBF fits into existing theory and models of privacy concerns. This is due, at least in part, to the lack of validated instruments to asse...
