Fat Tails
A fat-tailed distribution is a probability distribution that has the property, along with the heavy-tailed distributions, that they exhibit extremely large skewness or kurtosis. This comparison is often made relative to the ubiquitous normal distribution, which itself is an example of an exceptionally thin tail distribution, or to the exponential distribution. Fat tail distributions have been empirically encountered in a fair number of areas: economics, physics, and earth sciences. Fat tail distributions have power law decay in the tail of the distribution, but do not necessarily follow a power law everywhere.

Famous quotes containing the words fat and/or tails:
“O why do you walk through the fields in gloves,
Missing so much and so much?
O fat white woman whom nobody loves,
Why do you walk through the fields in gloves,
When the grass is soft as the breast of doves
And shivering sweet to the touch?”
—Frances Cornford (1886–1960)
“Panache upon panache, his tails deploy
Upward and outward, in green-vented forms,
His tip a drop of water full of storms.”
—Wallace Stevens (1879–1955)
