Should it be $\operatorname{Var}X$ or $\operatorname{D}X$ ? Moreover I think that $\xi$, $\zeta$ is more appropriate for random variables then $X$, $Y$. What do you think? --Nikita2 (talk)
- Yes, $\operatorname{Var}X$, as noted in the "Comments". About $\xi$, $\zeta$ I am neutral; also $X$, $Y$ are OK with me. --Boris Tsirelson (talk) 08:55, 23 February 2013 (CET)
