Quarterly Journal of the Royal Meteorological Society, EarlyView.Long‐term disdrometer observations are utilized to derive Z–R relationships for ‐the Western Pacific tropical cyclones. A hybrid moment‐based approach is employed to determine the interrelationships among pairs of gamma distribution parameters. Enhanced estimates of rainfall rate and slope parameter are obtained using machine‐learning techniques ...

Gini coefficient as a life table function
Demographic Research, 2003 This paper presents a toolkit for measuring and analyzing inter-individual inequality in length of life by Gini coefficient. Gini coefficient and four other inequality measures are defined on the length-of-life distribution.

Dynamic Research on China's Gini Coefficient [PDF]
Proceedings of the 2016 International Conference on Humanities and Social Science, 2016 Based on the grouped data of resident income in Statistical Yearbook, the paper calculates the China’s Gini coefficients of urban, rural and national residents in the ten years from 2002 to 2011 according to the characteristics of income data of urban residents and rural residents, and finally analyzes the Gini coefficients of urban, rural and national

DEFINING POVERTY LINES AS A FRACTION OF CENTRAL TENDENCY [PDF]
We show under lognormality that, when the Gini coefficient is stable over time, defining the poverty line as a fraction of a central tendency of the living standard distribution restricts the evolution of the poverty measures to be stable.

Quality and Reliability Engineering International, EarlyView.ABSTRACT Percutaneous transhepatic biliary drainage (PTBD) catheter placement is known to have a high readmission rate. This work focuses on monitoring the change in readmission rate after a new clinical paradigm for post‐procedural care is implemented for the PTBD procedures.

Journal of Field Robotics, EarlyView.ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Evidence for the exponential distribution of income in the USA
, 2000 Using tax and census data, we demonstrate that the distribution of individual income in the USA is exponential. Our calculated Lorenz curve without fitting parameters and Gini coefficient 1/2 agree well with the data.

Remote Sensing in Ecology and Conservation, EarlyView.A comparison of Convolutional Neural Network (CNN) and Random Forest (RF) model predictions of benthic habitats within Apollo Marine Park. The CNN (left) and RF (right) classification maps show the spatial distribution of three habitat types: high energy circalittoral rock with seabed‐covering sponges, low complexity circalittoral rock with non‐crowded

On Calculation of the Extended Gini Coefficient. [PDF]
The conventional formula for estimating the extended Gini coefficient is a covariance formula provided by Lerman and Yitzhaki (1989). We suggest an alternative estimator obtained by approximating the Lorenz curve by a series of linear segments.
