Monitoring vegetation growth and exploring the driving force behind it is very important for study of global climate change ecological environmental protection. Based on Normalized Difference Vegetation Index (NDVI) data from Moderate-Resolution Imaging Spectroradiometer (MODIS), meteorological nighttime lights 2001 to 2020, this uses Theil–Sen slope test, Mann–Kendall significance Rescaled Ran...

This paper introduces a conditional extreme value volatility estimator (EVT) based on highfrequency returns. The relative performance of the EVT is compared with the discrete-time GARCH and implied volatility models for 1-day and 20-day-ahead forecasts of realized volatility. This is also a first attempt towards detecting any time-series variation in extreme value distributions using high-frequ...

Fitting two-dimensional conic sections (e.g., circular and elliptical arcs) to a finite collection of points in the plane is an important problem in statistical estimation and has significant industrial applications. Recently there has been a great deal of interest in robust estimators, because of their lack of sensitivity to outlying data points. The basic measure of the robustness of an estim...

To achieve a balanced and sustainable rural development pattern, this study used the Theil index, Gini coefficient, Spatial Autocorrelation method to analyze inequality of industrial economic between areas in South Korea. The results showed that considering whole Korea, level among was reasonably balanced, trend narrowing. Considering first-level regions, levels varied. around Capital Area Metr...

A leading multivariate extension of the univariate quantiles is the so-called “spatial” or “geometric” notion, for which sample versions are highly robust and conveniently satisfy a Bahadur-Kiefer representation. Another extension of univariate quantiles has been to univariate U-quantiles, on the basis of which, for example, the well-known Hodges-Lehmann location estimator has a natural formula...

Relative price variability leads to inefficiencies in the allocation of resources that reduce real income (Fischer, 1981). Given the costs associated with relative price variability, the relation between inflation and relative price variability has been extensively researched and a positive relation between the two is documented for many countries and for varying time periods. Investigating the...
