External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on Total variation distance of probability measures. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

Added archive https://web.archive.org/20080708205758/http://www.stat.berkeley.edu/%7Esourav/Lecture2.pdf to http://www.stat.berkeley.edu/~sourav/Lecture2.pdf

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Relation to L1

"When the set is countable, the total variation distance is related to the" -> not only when the set is countable. This characterization (known as Scheffé's identity) also holds in the continuous setting (see. e.g., Theorem 5.1 of Combinatorial Methods in Density Estimation by Luc Devroye, Gabor Lugosi (2001).

Minus not showing

For some reason, the minus sign inside the formula is not displayed. — Preceding unsigned comment added by David cian (talk • contribs) 21:24, 15 January 2021 (UTC)[reply]

"Definition" not easy to understand

The current definition is hard going. Anyone feel like recasting the definition in easy to understand text?

I think I understand the graph. Could we at least put that definition first? W102102 (talk) 18:30, 14 July 2024 (UTC)[reply]
