"The Cauchy distribution is important as an example of a pathological case. Cauchy distributions look similar to a normal distribution. However, they have much heavier tails. When studying hypothesis tests that assume normality, seeing how the tests perform on data from a Cauchy distribution is a good indicator of how sensitive the tests are to heavy-tail departures from normality. Likewise, it is a good check for robust techniques that are designed to work well under a wide variety of distributional assumptions."
"Sono tre gli stati mentali che mi interessano", disse Amanda. "E sono: primo, l'amnesia; secondo, l'euforia; terzo, l'estasi. Amnesia è non sapere chi sei e desiderare disperatamente di scoprirlo. Euforia è non sapere chi sei e infischiartene. Estasi è non sapere esattamente chi sei... e infischiartene ugualmente". |
