Talk:Skewness of Hat-Check Distribution

suspicion
I calculated the skewness of $X$ with Excel&#x2122; function. The result is $0$ for $n = 2$, and $-1$ for $n = 3, 4, 5$. (The page says this function requires at least only one parameter above, but at least $3$ data below. BTW  for $n = 2$.) When $n = 1$, $\var X = 0$ (See Talk:Variance of Hat-Check Distribution) so the skewness of $X$ is not defined.

In addition, Poisson Distribution Approximated by Hat-Check Distribution seems to help examine the hat-check distribution. The skewness of $Y = n - X$ seems to approach Skewness of Poisson Distribution $= 1$ as $n \to \infty$. --Fake Proof (talk contribs) 15:46, 7 April 2022 (UTC)


 * Completely agree. I messed up. I should have checked this like you did. Thanks for the review!! --Robkahn131 (talk) 15:26, 9 April 2022 (UTC)
