Robust Wild Bootstrap for Stabilizing the Variance of Parameter Estimates in Heteroscedastic Regression Models in the Presence of Outliers

Abstract: Nowadays bootstrap techniques are used for data analysis in many other fields like engineering, physics, meteorology, medicine, biology, and chemistry. In this paper, the robustness of Wu (1986) and Liu (1988)'s Wild Bootstrap techniques is examined. The empirical evidences indicate that these techniques yield efficient estimates in the presence of heteroscedasticity problem. However, in the presence of outliers, these estimates are no longer efficient. To remedy this problem, we propose a Robust Wild Bootstra… Show more

“…( 3) The weighted bootstrap can be found in many recent applications: Bücher and Dette (2010) approximated the empirical copula process with it; Davidson and Flachaire (2008), Feng et al (2011) and Rana et al (2012) exploited weighted bootstrap in regression analysis.…”
