WebThe lower tail contains the lower values in a distribution. If you graph any distribution on a Cartesian plane, the lowest set of number will always appear on the left, because the lowest values on a number line are to the left. So, “lower tail” means the same thing as “left tail”.

"WebThe tail index, or tail exponent, α, characterizes the rate of tail decay if the tail goes to zero, in essence, like a power function, i. e., \({\bar{F}(x) = x^{-\alpha}L\left(x\right)}\), where L is slowly varying. Moments of order lower (higher) than α are (in)finite. " - Scaling property of tail decay
