Última Confidence intervals for rank statistics: Somers' D and extensions AgEcon Newson, Roger. Somers’ D is an asymmetric measure of association between two variables, which plays a central role as a parameter behind rank or nonparametric statistical methods. Given predictor variable X and outcome variable Y , we may estimate DYX as a measure of the effect of X on Y , or we may estimate DXY as a performance indicator of X as a predictor of Y. The somersd package allows the estimation of Somers’ D and Kendall’s τα with confidence limits as well as p-values. The Stata 9 version of somersd can estimate extended versions of Somers’ D not previously available, including the Gini index, the parameter tested by the sign test, and extensions to left- or right-censored data. It can also estimate stratified versions of Somers’ D, restricted to pairs in the...

The aim of this paper is to analyze the evolution of income concentration in the Brazilian rural area after the promulgation of the 1988 legislation and laws that followed under the security of the rural worker (Law 8212/91 and Law 8213/91). The methodological procedures involved the review of legislation, the verification of participation and the extent of concentration of pensions in rural income distribution after exposure of Law 8213/91 and debate in the literature. It uses the decomposition of the Gini index to measure income distribution, based on microdata from PNAD 1988 to 2008. The survey results have revealed that there was a reduction in the income concentration, from 0.559 in 1988 to 0.498 in 2008, partly explained by changes in the rural labor...
