Theil-Sen regression analysis is the most preferred method in non-parametric analysis. In method, calculations are made with median parameter. this study, it was proposed to calculate trimean parameter instead of way, effects outliers data on model fully reflected. applications one real-life and two simulation data, results obtained use were more successful. It recommended structures an excess ...

This method was adopted since all errors ...

Eco-efficiency is a tool for sustainability analysis that indicates how to carry out economic activities effectively. This paper assesses agricultural eco-efficiency using data envelopment analysis (DEA) and the Theil index approach. Using basic data of 31 provinces in China during 2003–2013, we analyzed the agricultural eco-efficiency development level and spatial pattern in China. The results...

In this study, ETo was calculated using FAO-56 Penman Monteith method. Lag-1 autocorrelation coefficient was performed to detect the presence of serially correlation in data series. Mann-Kendall (MK) or Modified Mann Kendall (MMK) and Spearman’s rho test were applied to detect the trend in annual and monthly ETo at 8 districts over 49 years (1960–2008) in the Soenath river basin, Chhattisgarh (...

This paper discusses the dynamic properties of generalized entropy measures of inequality, deriving an explicit expression linking changes in inequality with changes in the growth income. This establishes a time-wise decomposition for the family of generalized entropy measures of inequality, showing that the rate of change in the distribution of income can be divided into two parts. One is pure...

With support of GIS tools and Theil index, the spatial variance of urban energy consumption in China was discussed in this paper through the parallel comparison and quantitative analysis of the 30 provincial capital cities of mainland China in 2005, in terms of scale, efficiency and structure. The indicators associated with urban energy consumption show large spatial variance across regions, po...

Regression analysis is one of the most commonly used estimation methods. In statistical studies, some assumptions must be fully met to make good estimations with regression analysis. Some these are not always fulfilled in real life data. For such cases, alternative methods used. One them Theil-sen method, which non-parametric techniques. this study, different techniques were proposed by using w...

Regional economic inequality is a persistent problem for all nations. Meanwhile, satellite-derived night-time light (NTL) data have been extensively used as an efficient proxy measure for economic activity. This study firstly proposes a new method for correction of the NTL data derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard the Suomi National Polar-orbiting Partnershi...
