Formulas are derived for the Gini, Theil and Pietra coefficients a population-weighted mixture of double Pareto–lognormal (dPLN) distributions; they applied to South America 2 years. Results also provided special case lognormal distributions. The formulas useful measuring regional or global inequality in large-scale projects that utilise dPLN distributions their cases.

This study aimed to examine the spatiotemporal seasonal and annual trends of rainfall indices in Perak, Malaysia, during last 35 years, as any or spatial variability may influence regional hydrological cycle water resources. Mann–Kendall Sequential (SMK) tests were used assess trends. Precipitation concentration index was estimate variations concentration, Theil–Sen’s slope estimator determine ...

Abstract This paper examines human capital inequality and how it relates to earnings in Portugal using data from Quadros de Pessoal for the period 1986–2017. The objective is threefold: (i) show distribution of has evolved over time; (ii) investigate association between inequality; (iii) analyse role returns schooling, together with inequality, explanation inequality. Our findings suggest that ...

Accelerating the high-quality integrated development of digital economy and marine is vital for in coastal countries regions. However, few scholars examined such coordination. Here, based on panel data from 2012 to 2019 spatial scale China’s provinces cities, entropy method, coupling harmonious degree model (CCDM), Theil index, Tobit were adopted measure calculate interval index differences eco...

The continuous growth of urban agglomerations in China has increased their complexity as well vulnerability. In this context, resilience is critical for the healthy and sustainable development agglomerations. Focusing on Beijing-Tianjin-Hebei (BTH) agglomeration, study constructs an evaluation system based four subsystems: economy, society, infrastructure, ecology. It uses entropy method to mea...
