Lower tail probability

WebThe result (cdf(ts)) is the probability that the test statistic is equal to or less than that value actually observed based on your sample under H 0. For a lower-tailed test, the p-value is equal to this probability; p-value = cdf(ts). For an upper-tailed test, the p-value is equal to one minus this probability; p-value = 1 - cdf(ts). WebGeneral upper and lower estimates are given for the lower tail probability P(supt∈S(Xt −Xt0) ≤ x) P ( sup t ∈ S ( X t − X t 0) ≤ x) as x→ 0 x → 0, with t0 ∈ S t 0 ∈ S fixed. In particular, sharp rates are given for fractional Brownian sheet. Furthermore, connections between lower tail probabilities for Gaussian processes ...

The 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”. See more The “tails” of a distribution are, just like the name suggests, the appendages on the side of a distribution.
