Figure 1From: Testing for differences in distribution tails to test for differences in 'maximum' lifespanThe left graph is the density for control group (X = 0), 0.9*Weibull(5.73, 106.6)*I(X ≤ 130) + 0.1*Weibull(5.40, 100.06)*I(X > 130), and the right graph is the density for treatment group (X = 1), 0.9*Weibull(5.73, 106.6)*I(X ≤ 130) + 0.1*Weibull(5.45, 130.06)*I(X > 130), where P(Y > τ|X = 1) = P(Y > τ|X = 0) and yet the average magnitude by which lifespans exceed τ when X = 1 is different than when X = 0. τ is 90th percentile of the all observations in treatment and control groups.Back to article page
