摘要：
We develop a simple test for deviations from power law tails. Actually, from the tails of any distribution. We use this test – which is based on the asymptotic properties of the empirical distribution function – to answer the question whether great natural disasters, financial crashes or electricity price spikes should be classified as dragon-kings or ‘only’ as black swans.
