This page explains the formula for population and sample skewness. You can easily calculate skewness in Excel using the Descriptive Statistics Calculator. If you don't want to go through the lengthy derivation and explanation below, the formulas are here: Population Skewness Formula: Sample Skewness...
We derive approximate formulae for the skewness and kurtosis of the maximum likelihood estimator in the one-parameter exponential family. The key idea underlying these formulae is that they indicate when the normal approximation usually employed with maximum likelihood estimators can be misleading in sm...

This paper provides the derivation of the hitting time density of an Ornstein-Uhlenbeck process to a flat boundary. The derivation relies on a change of measure approach and delivers an explicit formula. This formula is an amended expres... B.,Leblanc,O.,... - 《Finance & Stochastics》 被...
Of course I don't know for sure how adequate our literature searching skills are, so I am still curious to see if someone finds an earlier derivation predating Smołalski's paper. --Eric Weeks Reply permalink report #3 David C. Norris comment accepted June 2024 Thank you, Eric! I ...
Building on this idea, the theoretical derivation by Henderson et al. [2004] yields a linear relationship between the near-bed skewness and the free stream asymmetry. On one hand, the phase difference between the free-stream and the near-bed flow is assumed to be frequency-independent. This ...
