WebAn abundance of high quality data sets requiring heavy tailed models necessitates reliable methods of estimating the shape parameter governing the degree of tail heaviness. The Hill estimator is a popular method for doing this but its practical use is encumbered by several difficulties. We show that an alternative method of plotting Hill estimator values is more … WebThe test is simply based on the confidence interval derived from the (asymptotic) normal distribution of Hill’s estimator, Again, if =2, we clearly rejct the assumption of infinite mean, and similarly, if =1.5 (finite mean, but infinite variance) Here the test is more robust than the one based on the GPD. WebG. Hill Plot The degree of cooperativity can be characterized by the Hill coefficient (n) which is the slope of the Hill plot at log(θ)=0. The Hill plot is a plot of : logθversus log[L].
