[edit] Graphical representation

I'm thinking of adding a graphic to this page.. something like a quantile quantile plot, because as a non-mathematician, this speaks to me in much clearer terms than sigma notation. Tombadog (talk) 23:30, 31 December 2007 (UTC)

Sure, that'd be useful. It's fairly common in the literature to accompany uses of the K-S test with some sort of graphical plot (e.g. a percentile plot) to make the point more clearly as well. --Delirium (talk) 10:34, 14 January 2008 (UTC)

[edit] Vodka Test

Michael Hardy has deleted the name "vodka test" from the Kolomogorov-Smirnov article. But "vodka test" is a legitimate name that I've heard used. I think this name gets used because it's more memorable to english-speaking students than long Russian names. That's why it should be mentioned on the Wiki K-S page too.

Googling around, I found that this name isn't as common as I supposed, but here are three references: a presentation mapping software documentation, and a professor's class handouts. I could also site a stats book where the term is used (in a joking way). Finally, from the google results I found, I suspect this term is used in the SPSS manual (though I haven't checked).

I haven't heard this before, but I think probably if this is included in the article, it should say that it is a jocular mnemonic. Michael Hardy 01:54, 21 April 2006 (UTC)


I haven't been able to find how to conduct a two sample KS test within one population of data. Does anyone know how this is performed? DC

A handful of people or publications have mentioned the Smirnoff "joke" but this does not make it universal, interesting, or relevant. I've never heard the K-S test called the vodka test.


What is the valu to compare the one i have found, what is the p-value for a specific significance value, the test seems incomplete.

[edit] The Anderson-Darling test

Under "Miscellaneous", the Anderson-Darling test is recommended as it is just as sensitive at the tails of the distribution as the median. I think that it needs to be explicit here, as it is in the opening paragraphs of the article, that the Anderson-Darling test is only for testing normality. Buzwad 12:58, 18 May 2007 (UTC)


[edit] Examples

It would be nice to have an example section that gives some detail on how to use the 2-sample K-S test. Dsspiegel 23:36, 18 October 2007 (UTC)Dsspiegel
