Errata: Tail Statistic Sample Calculation

Posted by kli_jcvi on 18 Nov 2014 at 22:44 GMT

There is a error in the example calculation for the Tail statistic on the bottom of page 13. The example equation should read:

tau = sqrt( 0.265(1-1)^2 + 0.196(2-1)^2 + ... + 0.007(13-1)^2)) = 3.764

In R code:

pr = c(0.265, 0.196, 0.145, 0.108, 0.080, 0.059, 0.044, 0.032, 0.024, 0.018, 0.013, 0.010, 0.007);
tau = sqrt(sum(pr*((1:length(v))-1)^2));
tau;

> tau;
[1] 3.763908

Sorry for any inconvenience.
