Asymptotic normality of non-parametric estimator for the FGT poverty index with when the parameter is strictly between 0 and 1. (English. French summary) Zbl 1356.60033

Summary: In this paper, we study the kernel estimator of Foster, Greer and Thorbecke class of measures when the poverty aversion parameter is strictly between zero and one, as a genreralization of the work of G. Dia [J. Math. Sci. Adv. Appl. 3, No. 1, 21–39 (2009; Zbl 1276.62103)]. We solved an open problem arising in mentioned paper. The asymptotic normality of the estimator is established. As an illustration, we determine the confidence intervals for different regions of Senegal. The study of this application demonstrated that our methodology is not only more efficient than the empirical estimator, but it also provides better confidence intervals for the poverty index.
