Enhancing SpatialHadoop with Closest Pair Queries
Given two datasets P and Q, the K Closest Pair Query (KCPQ) finds theK closest pairs of objects from P×Q. It is an operation widely adopted by many spatial and GIS applications. As a combination of the K Nearest Neighbor (KNN) and the spatial join queries, KCPQ is an expensive operation. Given the increasing volume of spatial data, it is difficult to perform a KCPQ on a centralized machine effi...
متن کاملDensity-Based Skewness and Kurtosis Functions
New, functional, concepts of skewness and kurtosis are introduced for large classes of continuous univariate distributions. They are the first skewness and kurtosis measures to be defined directly in terms of the probability density function and its derivative, and are directly interpretable in terms of them. Unimodality of the density is a basic prerequisite. The mode defines the centre of suc...
متن کاملSkewness in Hedge Funds Returns: Classical Skewness Coefficients vs. Azzalini’s Skewness Parameter
Recent literature discusses the persistence of skewness and tail risk in hedge fund returns. The aim of this paper is to suggest an alternative skewness measure which is derived as the normalized shape parameter from the skew-normal distribution. First, we illustrate that the skew-normal distribution is better able to catch the characteristics of hedge fund returns than the normal distributio...
متن کاملA 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...
متن کاملInstitutional Skewness Preferences and the Idiosyncratic Skewness Premium∗
This study examines whether idiosyncratic skewness preferences of institutional investors influence stock returns. On aggregate, institutions exhibit an aversion for idiosyncratic skewness but prefer systematic skewness, and in the cross-section, larger (smaller) and more (less) diversified institutions exhibit stronger (weaker) aversion for idiosyncratic skewness. The aggregate institutional p...
